Manchester United midfielder Michael Carrick says Sir Alex Ferguson's final farewell after their draw at West Bromwich Albion was matter-of-fact.

Carrick confirmed Ferguson has approached the fortnight since his retirement was confirmed in the same unemotional manner in private as he has in public.

"It has been business as usual," he said.

"He said a few thank yous after the game but generally it is as everyone has seen.

"He will have mixed emotions because it is a strange time for him, as it is for everyone at the club."
