SCOTT Brown believes Kieran Tierney could be playing Champions League football with European super clubs Barcelona or Paris Saint-Germain within a couple of seasons if he performs well with Arsenal, writes Matthew Lindsay

Brown was devastated to see Scotland left back Tierney, inset, leave the treble treble winners for the Premier League club in a record-breaking £25 million transfer last Thursday.

But the Parkhead skipper, who is set to face CFR Cluj in the second leg of the Champions League third qualifying round in Glasgow tonight, has formed a close friendship with the 22-year-old in recent seasons.

He hopes that Tierney performs well at the Emirates Stadium and feels that if he does shine for Unai Emery’s team then he will become a target for clubs further afield in future.

“You don’t know what could happen,” he said. “He could have a fantastic couple of seasons and end up at Barcelona or PSG or wherever.”

Brown was disappointed to learn that Tierney, who was a lifelong Celtic supporter as well as a player, had been attacked for deciding to join Arsenal by a section of the Parkhead support.

“There are pictures on the wall all over the club of players who have left and everyone would wish them all the best,” he said. “They can come back as well, that’s what this cub is all about.

“I see Ajax bringing players through and selling them on - and they have a party for them leaving. We try and criticise. It’s a different level.

“We wish him all the best. We just concentrate on now and Boli (new left back Bolingoli) has to push on and try to get to the levels that Kieran did.”
