The England international has stated that playing in the middle is his preferred situation, but says he is willing to play at the back if his manager and team need him to
The England international is at his best as a central midfielder and has been used there for the majority of his tenure at the Red Devils.
But due to a host of injuries to Manchester United defenders, manager Sir Alex Ferguson has occasionally opted to start Carrick as a centre-back and the 31-year-old admits the situation is inconvenient but something that has to be done for the good of the team.
"Ideally, I would like to play midfield because that is my position but if I've got to play at the back, then so be it," Carrick told reporters.
"I have played there three or four times this season. If there are injuries or whatever, part of playing for this club is to do what the manager wants.
"I don't have a problem with it."
Carrick was deployed in defence during Manchester United's 1-0 Champions League defeat to Galatasaray on Wednesday. However, the England international may not be needed as defensive cover for too much longer as Johnny Evans and Nemanja Vidic are expected to return from injury in the near-future, with Chris Smalling and Phil Jones having recently made their comebacks.
