Sven Bender is a doubt for Borussia Dortmund's game against Hoffenheim on Sunday with a muscle problem.
Coach Juergen Klopp is not entirely sure as to whether Bender has a tight muscle or whether he has a strain and remains hopeful.
"Sven is feeling good. I have said to him that it would be brilliant were he able to play on Sunday," Klopp told the club's official website.
However, the player himself was less optimistic.
"I don't think I will make it in time for Sunday," he is quoted as saying in Bild.
Should Bender fail to recover in time, Klopp will look to either Mario Goetze, who replaced Bender against PSG, or Antonio Da Silva to deputise alongside Nuri Sahin in central midfield.
