On July 15, 2019, Celtic turned down a second bid from Arsenal for Scotland left-back Kieran Tierney, worth approximately £25m.
The English Premier League club had previously had an offer of £15m rejected and had been optimistic a deal could be reached for the 22-year-old.
Tierney, who has been linked with Italian club Napoli, is currently recovering from a double hernia operation and missed Celtic's opening Champions League qualifier against Sarajevo.
He would become the most expensive player in Scottish football history if the deal goes through, surpassing the £19.7m Celtic received when striker Moussa Dembele joined Lyon in August 2018.
Tierney has won four league titles, two Scottish Cups, and two League Cups for Celtic, but has been restricted to nine appearances this year.
Meanwhile, a group of influential Arsenal supporters' organisations, fanzines, and blogs have joined forces to call for 'better leadership' of the club and criticise Stan Kroenke's 'passive ownership'.
