Arsenal have reportedly not given up their hopes of securing the signature of 22-year-old Celtic defender Kieran Tierney.
An initial bid of £15m from the Gunners was reportedly turned down by the Scottish champions, but it is expected that Unai Emery will increase his offer this week.
The young full-back has already made 170 appearances for the Glasgow giants and has represented Scotland 12 times.
The Mirror reports that Arsenal could be set to increase their offer to £22m, closer to Celtic's valuation which is believed to be £25m.
The report also suggests that Napoli are interested in signing the Scotsman.
Emery will be looking to strengthen his defensive options ahead of the new campaign after his side conceded 51 goals in the 2018-19 season.
