Arsenal are reportedly preparing a new offer for Celtic defender Kieran Tierney as the Gunners look to complete a deal for the Scotland international before the transfer window slams shut.
Unai Emery's side are believed to have had two separate bids rejected by Celtic for the left-back, who is nearing a return to training following a double hernia operation.
However, according to Sky Sports News, the Premier League club are expected to make a new offer in the hope of striking a deal with the Scottish champions before the August 8 deadline.
Tierney made 40 appearances for the Hoops in all competitions during the 2018-19 campaign but has not yet turned out for Neil Lennon's side this season as he steps up his rehabilitation from his double hernia procedure.
Arsenal will complete their preparations for the 2019-20 campaign against Barcelona on Sunday night ahead of their Premier League opener away to Newcastle United next weekend.
