The Scotland left-back will prove to be a bargain for the Gunners and has been backed to shine with his defensive qualities by the ex-Wales striker

Former Arsenal and Celtic star John Hartson has backed Kieran Tierney to be a success at the Gunners and says that his £25 million ($30.5m) transfer fee was “cheap”.

The Scotland international defender moved south in the summer but injury has restricted his initial impact at the Emirates Stadium.

Hartson, though, believes the youngster will prove to be a shrewd addition for the north London outfit and says he already surpasses compatriot Andy Robertson, a Champions League winner, in some aspects of his game.

“Arsenal probably got him on the cheap if you look at the fact Manchester United paid £50m for Aaron Wan-Bissaka,” he told the Daily Record.

“Also, average players are going for £30m or £40m and Kieran is certainly not average.

“Celtic could have held out for another £5m or so but it is still good money they have banked, especially due to the fact he has come through the ranks and hasn’t cost the club a penny.

“He is worth £25m and he can excel in a different league because there’s a perception the Scottish league is just not as good.”

Tierney’s appearances for Arsenal to date have been limited by a hip injury, with the 22-year-old having featured only twice for the starting XI and still waiting on his Premier League debut.

Nevertheless, Hartson believes he will be a hit once he gains his fitness.

“Once Kieran finds his feet he will do well. Nobody wants to go to a new club injured and not to be playing,” he explained.

“Kieran is a proud boy and he will be wanting to prove to everyone what a good player he is.”

Indeed, the former Wales international believes that Tierney is stronger in some aspects of the game that compatriot Robertson, who has won widespread acclaim at Anfield since joining the club in 2017.
