Arsenal have launched a bid to sign Celtic sensation Kieran Tierney, according to a report.

The 18-year-old has caught the eye of some of the biggest Premier League clubs on the back of a brilliant debut season that ended with him sweeping the boards with Scotland’s Young Player of the Year awards.

Football Insider revealed in early April that Liverpool were closely monitoring the left-back as they eye reinforcements on the left side of their defence.

The Daily Record claim that Arsenal are now weighing up a £10million offer for the highly-rated teenager even though Celtic chief executive Peter Lawwell claimed last week that the club are set to extend his contract this summer.

It is said that the Gunners have been closely monitoring Tierney’s performances and the club have received such glowing reports that Arsene Wenger has even sent his chief scout Steve Rowley to make personal checks.

The feedback from Wenger’s chief recruitment lieutenant is such that there is a growing possibility of a massive bid from the Londoners.

Lifelong Celtic fan Tierney has indicated he is keen to sign a new deal with his boyhood club although Arsenal’s strong interest could change his mind.

The 18-year-old still has three years to run on his existing contract but the Scottish giants want to reward the huge progress he has made this season.

Celtic chiefs are planning to extend Tierney’s deal until 2021 and hand him a significant pay rise.

Lawwell is hopeful the new contract for the teenager can be secured within weeks to fend off interest from the players’s growing number of suitors.

“Kieran has three years left after the summer,” Lawwell told the Scottish Sun last week. “He’s done brilliantly well and normally when that happens we’ll sit down with them and try to reward them.

“We’ll do that with Kieran and look to extend his contract. I’m sure that’ll happen over the summer.

“The kid wants to stay and we’re eager for him to stay.”

Tierney was named the best young player at Celtic’s end-of-season ceremony and was also named PFA Scotland Young Player of the Year.

Tierney, 18, has enjoyed a whirlwind campaign in which he has made 33 appearances for the Scottish Premiership leaders and been handed a Scotland call-up.

He made his full Scotland debut against Denmark during the March international break despite never having pulled on a dark blue jersey for the Under-21s.

Tierney spoke just a fortnight ago of a desire to stay at Celtic Park for the long haul rather than make an early jump to England.

In other Arsenal transfer news, the club are ready to pay £65million to land one of their priority summer targets.
