However, Kroos, 23, has insisted that the acquisition will provide healthy competition at the club in the new campaign.
"It's Pep's job to assign Thiago to a position. I think he's a very good footballer and good footballers are always welcome," Kroos told Tageszeitung.
"In a team which has so much quality, a few very, very good players will have to sit on the bench, just like last season."
Kroos has 35 international caps for Germany to his name.
