The 19-year-old is earning rave reviews following his performances for Celtic and it looks as though the Scottish Premiership champions will face a fight to keep hold.

City boss Pep Guardiola was able to get a close-up look at the full-back when the two sides clashed in the Champions League, while Arsene Wenger has also ordered his scouts to check him out.

Tierney is said to be more than happy at Celtic, the club he has supported all of his life, and it remains to be seen if he could be lured south of the border.

Arsenal, who are also keen on Celtic striker Moussa Dembele, look sure to test the water with a bid when the transfer window re-opens in January and City could do the same.
