FC Barcelona are worried that Arthur’s level has dropped recently due to his body not keeping up with the demands of European football, according to Diario SPORT.
The paper says Arthur tends to be spent after about 70 minutes, which is why Ernesto Valverde subs him off almost every time. Even at Grêmio, his club in Brazil, he didn’t always last 90 minutes.
The Brazilian is doing his best to adapt his body, and he is said to be the player most often seen drinking protein shakes. He has suffered more injuries than one would hope, and in part it’s been because he’s taken some ill-advised decisions like choosing to attend Neymar’s birthday party in Paris before a match against Real Madrid.
