With the European Championships expanded to 24 teams this year, you would expect most major European club teams to have a few players at the tournament.
Yet, the fact that Sweden’s Mikael Lustig is Celtic’s sole representative at the tournament probably says a lot about the reasons why Ronnie Deila is no longer in charge at the club.
However, although there won’t be many current players for Celtic fans to follow, there are quite a number of former Hoops who will be gracing the tournament with their presence.

The Southampton stopper enjoyed four successful seasons at Celtic, including an incredible performance against Barcelona that earned him the nickname of ‘La Gran Muralla’ (The Great Wall).
He goes to the Euros on the back of a good season at Southampton, though he is likely to remain back-up to Joe Hart.

The Welsh vice-captain played for Celtic during the same period as Forster, from 2010 until 2014. Since then, he has been quietly but effectively plying his trade for Crystal Palace.
He will be hoping he can assist Gareth Bale in inspiring Wales to outperform expectations.
The pacey forward has enjoyed a successful spell at Aberdeen, following a move from Celtic in 2012. He is another who is unlikely to get too much game time, but will be hoping to get the chance to at least make some appearances from the bench. His pace could be useful late in games for Northern Ireland.
The ‘Holy Goalie’, as he was christened by Celtic fans, has travelled to France with the Poland squad. The current Bournemouth keeper was a huge fan favourite during his five seasons at Celtic Park.
In what seems to be a developing theme, he is yet another ex-Celtic backup goalkeeper at Euro 2016. At 36-years-old, he still has the quality to perform at the top level if called upon.
The young Belgian is one of the less experienced players in Belgium’s star studded squad at the Euros. The classy centre-half will be competing with the likes of Jan Vertonghen, Thomas Vermaelen and Toby Alderweireld for a place in the starting line-up.
Currently contracted to Manchester City, Denayer has spent the last two seasons on loan at Celtic and Galatasaray respectively.
Ireland's McGeady was Scottish football’s most expensive export when he left Celtic for Spartak Moscow in 2010. Since then, he has had mixed success. He returned to the UK with Everton in 2014, and spent a relatively unsuccessful loan period with Sheffield Wednesday this season.
It remains to be seen whether Martin O’Neill will still consider McGeady to be one of the first names on the team sheet, but he should make an appearance at some stage.
Irish legend Keane spent a six-month loan spell at Celtic in 2010. He looked a class above most of his team mates and opponents as he scored 12 goals in his 16 appearances. Now playing with LA Galaxy, he travels to the Euros hoping to further increase his record tally of 67 goals for Ireland.
Interestingly, this makes him the player with the highest number of international goals at the tournament, ahead of the likes of Zlatan Ibrahimovic and Cristiano Ronaldo.
Another former Celt heading to the Euros with Ireland, Murphy was at Celtic for three years in total, but spent two of those on loan at Ipswich Town, where he later moved permanently.
He was never prolific at Celtic, scoring just three goals in 19 appearances, but now finds himself with a part to play in Europe’s showcase international tournament. He probably won’t start games, but might get some game time from the bench.
The charismatic Swede spent a season on loan at Celtic Park in 2014-15. He traversed between looking world-class and relatively anonymous, but was generally a success. Now with Celta Vigo in Spain, Guidetti finds his place in the Swedish starting line-up blocked by the considerable presence of one Zlatan Ibrahimovic. Nonetheless, he has a good chance of getting some pitch time during the tournament, where he will hope to add to his solitary international goal.
