The first-team refresh is already underway with a €75-million move for Ajax wunderkind Frenkie de Jong. Rumors also link Barcelona with interest in Eintracht Frankfurt goal machine Luka Jovic, Atletico Madrid star Antoine Griezmann, and de Jong's teammate Matthijs de Ligt.
Barcelona are apparently willing to ship Coutinho for a bid of more than €100 million. Arsenal are reportedly in for Umtiti under the assumption that the French World Cup winner could become surplus to requirements at the Camp Nou amid Clement Lenglet's emergence and the De Ligt rumors.
Rakitic appears least likely to leave, especially as one of Valverde's favorites. Sources said that the Spanish tactician blocked the Croatian international's move to Paris Saint-Germain last summer.
Joining the top-tier trio on the way out could be Jasper Cillessen, Rafinha, Andre Gomes, and Denis Suarez, with the latter two currently on loan in the Premier League. Malcom, who enlisted with the Catalans last summer from Bordeaux on a €40-million transfer, has also been linked with an exit.
