Arsenal to offer fresh bid of £20m 'plus add-ons' for Kieran Tierney - reports

It is being reported that Arsenal are set to return with a fresh bid of £20m 'plus add-ons' for Celtic's Kieran Tierney.

As well as one of the club's best players in recent years, Tierney is a cult hero to the Celtic fans.

According to The Sunday Business Post, the London club is looking to test Celtic's resolve by meeting their valuation with a bid of around £20m plus £5m in add-ons.

Unai Emery then followed up a second bid of around £18m, which was once again knocked back by Celtic and described as derisory by former Celtic and Arsenal star John Hartson.

It now seems that the Arsenal boss is ready to take the plunge and try to meet Celtic's valuation for the vastly experienced player.

However, boss Neil Lennon has previously stated that Tierney is on a long-term contract, and that the club "don’t want to sell him".
