10 questions we have after Saturday's Premier League action

theScore examines the most important Premier League developments by answering 10 key questions that arose from Saturday's slate of action.

Is Harry Kane broken?

Remember when it felt like Harry Kane was a scoring threat every time he stepped foot on the pitch? It seems like a long time ago.

At his best, the 26-year-old striker is a shot monster who is equally adept both at finishing chances and helping create them for his teammates. He did neither on Saturday against Watford. If anything, he hindered Tottenham's attack, often killing the momentum of a move by picking the wrong pass.

Worse still, he had just three shot attempts. None of them hit the target - they were all blocked - and only one came from inside the penalty area. Spurs were poor (again) as a whole, but against a team that's now conceded a joint-worst 21 goals this season, you simply expect the English striker to be more influential. Maybe he's not truly overcome his myriad ankle injuries?

WYD, Watford?

If you want to know how bad teams stay bad, watch Watford play. The Hornets, stuck at the bottom of the Premier League table with a measly four points from nine matches, threw two points away - almost literally - in their 1-1 draw with Tottenham.

Fans will bemoan an apparent penalty that wasn't awarded despite a VAR check, but Watford have only themselves to blame for wasting multiple chances before Ben Foster gifted Dele Alli his late equalizer.

A handful of second-half counterattacks somehow yielded no clear-cut opportunities; multiple odd-man rushes were squandered by poor final passes, weak efforts on goal, or plain old poor decision-making. A wobbly Tottenham were there for the taking, and Watford whiffed.

Can Everton turn things around now?

That sound you hear is Marco Silva letting out a huge sigh of relief.

Everton ended their four-match league losing skid with a huge 2-0 victory over West Ham at Goodison Park, getting a crafty goal from Brazilian winger Bernard before Gylfi Sigurdsson secured the much-needed points.

"Pressure is normal in football, whether you are winning or losing. Our last few results were not good enough, so we had to react," Silva said after the match, per The Guardian. "We controlled the game and created a lot of chances. It was good to see."

The Toffees came into the season expecting to be in the fight for the proverbial "best of the rest" title. Instead, they went into the October international break languishing in the relegation zone. They're out of the bottom three now, but is this a turning point, or false dawn?

Can Hudson-Odoi and Pulisic play together?

Much has been made of Christian Pulisic's slow start to life at Chelsea; the American whiz kid has found himself either on the bench or omitted from the squad entirely of late.

Callum Hudson-Odoi's continued emergence is a reason for that, but Frank Lampard gave everyone a taste of what his side could look like with the two dribbling wizards on the pitch together Saturday. Granted, it was only lowly Newcastle, but the 21-year-old Pulisic and his teenage teammate wreaked havoc after the former was introduced as a second-half substitute.

Chelsea's winning goal came courtesy of a penetrative Pulisic run, as he flipped the ball over to his 18-year-old peer, who promptly teed up Marcos Alonso for the game's lone tally.

Should Willian start worrying about his place in the team?

Third-best side in the league?

Speaking of Chelsea, the Blues may be starting to put together a case as the third-best team in the Premier League. Their expected goal difference of 6.1 was behind only Manchester City and Liverpool prior to this weekend's impressive performance against Newcastle, in which the 1-0 scoreline doesn't truly reflect the one-way traffic we saw at Stamford Bridge.

Quite incredible, really, considering they were shackled in the summer transfer market.

Leicester City, who we'll get to shortly, have thrust themselves into that conversation as well, while Arsenal will look to regain third place in the table when they visit Sheffield United on Monday. There's a very clear chasm between the top two and everyone else, but the scrap to slot in behind them will be fascinating all season.

Who's going to score goals for Newcastle?

Newcastle have found the net just five times this season, and their expected goals total - which is a shade lower - is by far the worst in the Premier League after nine matches. It's ... not good.

No wonder fans of the impotent Magpies are pining for Salomon Rondon to return.

How long can Leicester keep hold of Tielemans?

Manchester United wasted a small fortune on Fred. Granit Xhaka is a lock to start every week for Arsenal. Europe's best sides are still circling around N'Golo Kante. Tottenham, despite impressive midfield additions this summer, could do with further upgrades as Christian Eriksen inches closer to an exit.

Meanwhile, Youri Tielemans continues to flourish at Leicester City.

The 22-year-old Belgian, part of the Foxes' wildly talented young core, scored an emphatic winner against Burnley, ghosting into the penalty area from midfield before unleashing a rocket off the underside of the crossbar.

A classy passer who can create chances and chip in with the odd goal, Tielemans should be on every big club's wish list heading into next summer.

And what about Grealish at Villa?

The same can be said of Aston Villa captain Jack Grealish.

The 24-year-old scored once and created the winner in Villa's last-gasp triumph over Brighton, while the six chances he created were more than any other player on the pitch.

He's come close to being poached before - Tottenham were the most aggressive suitor for his services - but even if Villa retain their top-flight status for next campaign, this season may be the last we see of the skillful No. 10 in claret and blue.

West Ham coming back down to earth?

In a word, yes.

The Hammers were flying high after last month's 2-0 win over Manchester United, but their results have cratered since then: West Ham are winless in four matches across all competitions, a stretch that includes a humiliating 4-0 loss in the League Cup to third-tier side Oxford United.

Manuel Pellegrini, who lamented his team's lack of effort after Saturday's loss to Everton, needs to turn things around quickly to ensure this rough patch doesn't turn into something more dire.

Can City survive all the defensive tinkering?

Pep Guardiola's tactical tinkering has been kicked into overdrive this season.

The curious decision not to invest in central defense over the summer came back to bite Manchester City in the backside when Aymeric Laporte and John Stones suffered injuries early in the campaign, leaving the impetuous Nicolas Otamendi as Guardiola's only fit center-back. With the Argentine nursing an ailment on Saturday, City rolled out a starting XI that saw holding midfielders Fernandinho and Rodri occupy the two spots at the heart of the backline.

It wasn't always perfect - Crystal Palace threatened in the second half - but it got the job done. Can City continue to keep Liverpool in touching distance with these types of makeshift lineups, though?

Rodri slotted back into his more natural role in the latter stages when Stones made his awaited return, and that's likely the setup we'll see moving forward until Laporte, who is nursing a serious knee issue, gets back on the pitch in 2020.
