Arsenal have made an improved offer in the region of £25m for Celtic left-back Kieran Tierney, as per reports.
Arsenal’s first bid of £15m was rejected three weeks ago.
Serie A side Napoli are also interested in a deal for the Scotland international.
The 22-year-old was restricted to 21 league appearances for Celtic last term.
Tierney, who is contracted to Celtic until the summer of 2023, was hampered by a hernia problem last season and is currently recovering from surgery.
