Atletico Madrid interested in Celtic defender Kieran Tierney

La Liga giants Atletico Madrid are reportedly interested in signing Celtic left back Kieran Tierney with scouts heading to Hampden this weekend to watch him play against Motherwell in the Scottish Cup Final.

The Spanish side are set to compete with Manchester United, Tottenham and Bournemouth for the £20 million-rated youngster, although Celtic are unwilling to sell one of their prized assets. The Europa League finalists Atletico are second in La Liga, three points clear of Real Madrid with one game to go.

The 20-year-old has been a regular first team player at Celtic since Ronny Deila handed him his debut in 2015 and has won nine caps for Scotland and captained both club and country during that time - winning three Scottish Premiership titles, a Scottish Cup and two League Cups. Along with winning the PFA Scotland Young Player of the Year award for three years running.

Just last week Tierney admitted that he is flattered by the attention but is happy to stay at his boyhood club for the long term, after signing a six year deal earlier this season.

He said: “When big teams are looking at you, it’s flattering. It’s happened during most windows since I broke through. It’s good for me. It doesn’t bother me or distract me because I’m enjoying myself.

“I’m playing for Celtic, so I’m happy. I’m not in any rush at all. I had four years left on my last contract and, if I wanted to leave, I would have chosen to run that down. Instead, when the club offered me six I was happy to sign.

“That’s three seasons I’ve been playing regularly for Celtic and that’s a long time. But I still see myself as being young and having a lot to learn. I’ve been around the dressing room and seen a lot of people come and go.”

Celtic can win historic back-to-back domestic trebles if they beat Motherwell at the weekend.
