With the Red Devils struggling at the back, Goal looks at those who have tried – and, in most cases, failed – to establish themselves at Old Trafford

Drafted in during the early days of Louis van Gaal's tenure amid a defensive injury crisis, Blackett was soon found to be out of his depth at the highest level, at both centre-back and left-back.
Sent out on loan to Celtic in a bid to gain more experience, he only made three appearances for the Bhoys before being sold to Reading in 2016.

Another who broke into the side during Van Gaal's first season, McNair's early performances saw him earn a call-up to the Northern Ireland squad.
However, he soon began to struggle and fell down the pecking order, eventually leaving in 2016 to join Sunderland, where he was last seen playing as a No.10!

Evans remained at the Theatre of Dreams for one season following the departure of Rio Ferdinand and Nemanja Vidic but, after an injury-hit campaign, he left for West Brom.
Needless to say, with Manchester City and Arsenal keen on signing him, it might have been better for United to keep hold of the Northern Ireland international.
