Arsenal have reportedly ended discussions with Celtic regarding the signing of defender Kieran Tierney.

The Gunners have spent the last few weeks attempting to strike a deal for the versatile full-back, who has been strongly linked with a move south of the border.

However, Celtic have indicated that they are only willing to part ways with arguably their most prized asset if his £25m price-tag is met by an interested club.

According to the Daily Record, Arsenal are against paying most of that fee in the coming weeks, instead preferring to pay in a number of instalments.

Celtic have refused to budge, however, which has seemingly led to Unai Emery opting to switch his attention of different targets.

The 22-year-old still has four years remaining on his contract.
