The Manchester United midfielder could find himself falling down the pecking order at Old Trafford.
Finally, a big name has been confirmed as Manchester United's new signing. Memphis Depay was one thing - an upcoming young talent who could develop into a world beater.
But Bastian Schweinsteiger is already a world beater. The German won the World Cup but a year ago and has won Bundesliga and Champions League titles during a hugely illustrious career.
Despite his age and recent injury record, his signing is a huge statement of intent - even if things don't work out at Manchester United.
And the fanfare that is likely to surround his arrival at Old Trafford may affect one man more than others. Indeed, could Michael Carrick be the biggest loser in all this?
According to the Manchester Evening News, United are still interested in Morgan Schneiderlin despite the Schweinsteiger deal. Will there be any room for 33-year-old Carrick when Schneiderlin, 25, and Schweinsteiger, 30, stake their claim for a place in Louis van Gaal's side?
Naturally, Carrick's recent injury record meant Manchester United absolutely needed a new midfielder this summer. But, should Schneiderlin still arrive at Old Trafford, both he and the German will add to competition fiercely.
There are already the likes of Ander Herrera and Marouane Fellaini in the mix, while Schweinsteiger's reputation suggests he will naturally be ahead of Carrick in the pecking order - despite the fact both have been injury prone of late and despite the fact the latter is hardly in the best form of his career.
A good signing for United, then, might just be a bad one for the 33-year-old. Can his form and fitness keep him in with a shout next season?
