Arsenal have submitted a new Kieran Tierney bid worth more than £20million as they clear the decks to prise him from Celtic, Football Insider has learned.

The Premier League giants have tabled a new offer made up of a guaranteed payment of £18million plus £5million in add-ons after their opening bid was rejected last month.

Sources at Arsenal have told Football Insider that the Londoners are hopeful the new bid will be enough to edge ahead of Napoli in the race for Tierney.

The club have earmarked Tierney for their left-back position next season and have ordered long-serving Nacho Monreal to find a new club.

The Spaniard, whose £70,000-a-week Arsenal deal is up for renewal, is expected to return to his homeland amid interest from Real Sociedad among other clubs in La Liga.

This will free up space on the London club’s wage bill which has been severely hit by their failure to secure a place in next season’s Champions League.

Football Insider revealed that Arsenal’s opening bid for Tierney was made up of £15million in cash as well as the offer of up to six different fringe players to the Scottish club.

Celtic want £25million for their prize asset, with manager Neil Lennon claiming that the Gunners’ first formal move for the 22-year-old was well short of their asking price.

The Hoops are hopeful of using Napoli’s interest in Tierney to squeeze more money from Arsenal in another twist to the developing saga.
