The Celtic left-back has impressed in the Scottish Premiership this season making 33 appearances in all competitions. Apart from being adept on the defensive side, the 19-year-old has also contributed with 12 assists which have attracted interest from a number of top-flight clubs in England.
Arsene Wenger is a big admirer of the left-sided defender and is keen to bring him to Arsenal in the summer as uncertainty surrounds the future of Kieran Gibbs, who will have just one year on his contract at the end of the season. Tierney will make a good understudy and potentially challenge current first choice Nacho Monreal for a spot in the starting XI.
Spurs are also reportedly interested in signing a left-back in the summer amid fears that Danny Rose could be lured away by the riches on offer at Manchester City, which will leave them with Ben Davies as the only option. However, according to the Manchester Evening News, both the north London clubs are set to be disappointed as Tierney favours a move to Manchester over the English capital.
Jose Mourinho is certain to strengthen his backline during the upcoming summer transfer window and left-back will be a position that needs filling after the manager questioned United's current full- back Luke Shaw's understanding of the game following their recent draw against Everton.
The England international has taken the Portuguese manager's criticism in his stride and vowed to fight for his place in the team, but the manager is likely to bring in a traditional left-back as backup after using a number of players – not regular left-backs by trade - in the full-back position during the course of the season.
