Europa League finalists Man Utd and Tottenham suffer home losses
Manchester United slumped to a 2-0 home defeat West Ham as their woeful league campaign hit a new low.
United were back in action after crushing Athletic Bilbao in the Europa League semi-final second leg on Thursday to set up an all-English final against Tottenham on May 21.
But Amorim has acknowledged United "can't save anything from the Premier League" this term and once again they produced a wretched display as West Ham won for the first time in nine games.
Tomas Soucek's 26th-minute tap-in from Mohammed Kudus's cross gave West Ham the lead.
United lost Leny Yoro to a foot injury in the second half, raising doubts about the French defender's chances of featuring in the Europa League final.
Jarrod Bowen converted Aaron Wan-Bissaka's pass to grab the second goal in the 57th minute.
West Ham moved above United, who are languishing in 16th place as they face their lowest league finish since being relegated in 1973-74.
Tottenham fared no better after reaching the Europa League final as Crystal Palace won 2-0 in north London.
Tottenham dispatched Bodo/Glimt on Thursday to book their place in the Europa League final.
But, under fire after a dismal domestic campaign, boss Ange Postecoglou could be sacked even if Tottenham win their first trophy since the 2008 League Cup.
Against a Palace side warming up for next weekend's FA Cup final against Manchester City, Postecoglou's men produced a miserable performance and fell behind when Eberechi Eze tapped in Daniel Munoz's cross on the stroke of half-time.
Eze struck again in the 48th minute as the winger took Ismaila Sarr's pass and drilled home.
Beaten 20 times in 36 league games, Tottenham are just one place above the relegation zone and are on the verge of their worst finish since being relegated in 1976-77.
