Arsenal manager Unai Emery has identified Kieran Tierney as a potential summer transfer target, according to the Mirror.
The 21-year-old is one of Celtic’s most highly-rated players and they will find it hard to keep hold of him in the coming months.
Emery is looking to strengthen in three key areas this summer and left-back is one of them.
Tierney is someone who can bring youth and quality to the Gunners’ back-line, with Nacho Monreal ageing and doubts surrounding Sead Kolasinac’s ability.
The Celtic favourite is also a target for Leicester City, with former Hoops manager Brendan Rodgers keen to take him to the King Power Stadium.
That is partly down to likely summer bids for Ben Chilwell, most notably from Premier League champions Manchester City.
The report does state that Rodgers’ controversial exit from Parkhead last month could work against Leicester, however, boosting Arsenal’s chances of landing the Scotland international.
Tierney’s current Celtic deal runs until 2023, so it will take a hefty bid to prise him away from the club.
Celtic's most expensive departures of all time
5. Aiden McGeady - £10.8m
A tricky winger who arguably never quite reached his potential, McGeady made a surprise move to Spartak Moscow in August 2010.
4. Fraser Forster - £11.25m
Forster was a key man between the sticks for Celtic, before heading to Southampton five years ago.
3. Victor Wanyama - £13m
Wanyama also opted to join Southampton in 2014 and he is now plying his trade at Tottenham.
2. Virgil van Dijk - £14.1m
What is it with Celtic and Saints?
Now arguably the world’s best defender at Liverpool, Van Dijk moved from Parkhead to St Mary’s Stadium back in 2015.
1. Moussa Dembele - £19.8m
The gifted striker traded Celtic for Lyon last summer, where he has scored 13 goals so far this season.
