Celtic are mulling over a second Arsenal bid for Kieran Tierney which will take the deal up to their £25million asking price.

The Gunners had their first move for the Scotland full-back rejected three weeks ago.

Now they've come back and upped the ante from their £15m opening salvo - and Peter Lawwell and the Hoops board are contemplating their next step over the weekend.

MailSport understands that while the deal doesn't give them the up-front figure they wanted, it does reach the trigger figure on appearance-based add-ons.

And with Neil Lennon already drafting in a £3million replacement in Boli Bolingoli-Mbombo, it’s believed the Emirates side are optimistic they can get the deal done this time.

Tierney has missed the start of the Celtic season through rehabbing from a double hernia op, and despite Neil Lennon revealing the 23-year-old is still nursing a pelvic inflammation, we understand he was working out with medical staff at Lennoxtown yesterday while the team played out a 0-0 friendly draw with Rennes.

Italian side Napoli were also in the hunt for the Celts-daft iron man, but despite their limited summer budget, Arsenal boss Unai Emery has kept the left back at the top of his priority list.
