According to former Celtic striker Frank McGarvey, if Kieran Tierney is to succeed in Europe, he will need to quit Celtic but at the right time.

Tierney has been hailed as the best left-back in Britain by McGarvey. According to the Evening Times, the Celtic full-back has been widely scouted over the last 20 months.

Tierney’s sparkling displays at Celtic this season have seen him garner a lot of attention from some of Europe’s top clubs, with the Evening Times claiming that Manchester United are one of the clubs interested in signing him at the end of the season.

However, McGarvey believes Tierney would be a much better fit at Manchester City or Tottenham Hotspur.

“Right now he is the best left-back in Britain, bar none,” McGarvey was quoted by the Evening Times. “To me a club like Manchester City who look like they could win something in Europe and who play in a style that suit Tierney would be an ideal club for him.

“Tottenham, too. They play an attacking style of play and we have seen them get better and better of late. To me that is the kind of team where he would slot right in but ultimately it is up to the boy himself.

“The next step he takes in his career is life-changing. Right now Celtic are all he knows and all he has ever known. He has been at the club since he was at primary school, he has gone through the ranks all the way to the first-team and he is still settled at home with his parents.

“Only he can decide what he wants. If it was me, it would come down to European football. The gap is getting wider all the time. Celtic are not going to invest in the team to the extent that it will make a huge difference to what they do in the Champions League.

“As a player that would be my motivation. But he seems like a sensible lad and he will know what is best.”

Tottenham boss Mauricio Pochettino has launched the careers of innumerable young talents. The likes of Harry Kane, Dele Alli, Kyle Walker, Danny Rose and many more have turned into full England internationals under his coaching and guidance.

The 20-year-old Tierney has performed remarkably well for the Hoops. The Scottish full-back has already played more than 100 times for Celtic in all competitions, winning a domestic treble last season.

Though Tierney signed a new six-year deal with Celtic last October, Spurs must take the gamble by launching a bid for the young star in summer. Tierney’s ability to play anywhere in the defence is an attractive option for Pochettino to consider

Since he’s won everything in Scotland, Tierney would do well to explore the Premier League for more success in his career.
