Arsenal are confident of signing Kieran Tierney for £18 million this summer, according to the Guardian.
The left-back is one of Celtic’s most prized assets, having matured into a top class player in recent years.
The 22-year-old would be a big loss if he did leave Parkhead, with interest in him no great surprise.
Arsenal have emerged has the front-runners to sign the defender this summer, as Unai Emery looks to add quality to his squad.
The Gunners have already had a £15 million bid for the Scotland international turned down by Celtic, but they believe £18 million could be enough to get their man.
The Hoops value Tierney at £25 million, but the player’s rumoured willingness to move to north London could see a smaller bid accepted.
Arsenal believe the youngster can have a similar impact to that of boyhood Celtic fan Andy Robertson at Liverpool, who has matured into one of Europe’s best left-backs.
Celtic's 5 most expensive deaprtures
5. Aiden McGeady - £10.8m
An unpredictable but talented winger, McGeady was a popular figure at Celtic.
He made a surprise move to Spartak Moscow back in 2010, costing £10.8 million.
4. Fraser Forster - £11.25m
Forster has to go down as one of Celtic’s best goalkeepers of the 21st century, following an impressive stint at Parkhead.
His good form earned him a move to Southampton, where he continued to shine.
3. Victor Wanyama - £13m
Wanyama was a dominant presence at the heart of Celtic’s midfield between 2011 and 2013.
He was another who moved to Southampton, before joining Tottenham.
2. Virgil van Dijk - £14.1m
What is it with Celtic selling their best players to Southampton?
The same happened with Van Dijk in 2015, following a colossal spell in Scotland.
He’s now at Liverpool, where he has arguably become the best centre-back on the planet.
1. Moussa Dembele - £19.8m
Dembele remains Celtic’s record departure, having traded the Hoops for Lyon last summer.
The striker excelled in France in his first season, scoring 20 goals in 45 appearances.
