Kieran Tierney is one of the hottest prospects in Britain at the moment and a host of clubs are interested in signing the Celitc star this summer.
Arsenal were mentioned as suitors for Tierney recently and now according to the Mirror, Manchester United have also joined the race for the left back.
It seems that the Red Devils are about to make an offer worth £15 million and that they are serious about bringing Tierney at Old Trafford.
The Hoops were believd to have had plans to sell star Moussa Dembele this summer, and secure some financial income which would allow them to keep together the rest of the team.
The latest developments and an enormous amount of money offered for Tierney by the two English giants though, may mean this plan will probably have to be changed.
The 20-year-old left back, has appeared 61 times in Celtics jersey and scored two goals. During the previous season, he played 31 matches, netting once.
At the moment he has a valid contract with the Hoops which would keep him until 2021 at Parkhead.
