Carrick has been appointed head coach at Manchester United until the end of the season
There are two versions of Michael Carrick the coach: the interim manager who took charge of Manchester United for three games and the Middlesbrough manager who spent three years in the Championship.

Five months, as interim head coach until the end of the season, lands awkwardly in the middle, so how might Carrick set United up?
BBC Sport looks at the principles, tactics and players Carrick and his staff could use by analysing his approach at Middlesbrough and in the three games he managed as United's interim in 2021.
