Luke Shaw has struggled with injuries this season and the Red Devils could make a signing at left-back in order to field a more consistent back four
Manchester United want to sign £10 million-rated Celtic defender Kieran Tierney, according to the Daily Mirror.
The Red Devils have lacked a consistent left-back this season, with Luke Shaw struggling to stay fit, and have identified Tierney as a potential long-term solution.
The 19-year-old is making his way back from an absence of his own with an ankle injury and is therefore more likely to be a summer target.
