Players linked to Chelsea, Arsenal and Manchester United are all in action in today's Group D and E encounters.
With the tournament now well underway, there is one match in Group D today to complete their first round of fixtures before Group E kicks off later in the day.
Holders Spain start the defence of their title against the Czech Republic in Toulouse in the early kick-off before the Republic of Ireland take on Sweden at the Stade de France. Belgium and Italy conclude the day's action when they meet in Lyon.
There will be plenty of familiar names on show given that every side has participants either strongly linked, well-known or plying their trade in the Premier League.
Here are three players to look out for in today's games:
With Spain pretty limited in terms of out and out centre forwards, it would not be a surprise to see Morata have a big role to play for the reigning European Champions this afternoon.
The Juventus forward has had a pretty successful time of things in Italy. He was crucial to the side's run to the 2015 Champions League final - although last season his return of 12 goals from 47 appearances in all competitions for his club was fairly modest.
However, the 23-year-old seems to be attracting interest from the Premier League - with Arsenal, Manchester United and Chelsea all credited with interest in the forward, according to the Daily Express, who cite other various reports.
There will not be a better scouting mission for incoming Chelsea boss Antonio Conte, as Nainggolan is due to line up against his Italy side for Belgium this evening - while he gets a closer look at one or two players he will have at his disposal as soon as he arrives in London.
Reports, including one from the London Evening Standard, indicate that Conte is keen on Nainggolan and that Chelsea will make a third bid for the Roma star. It will be an interesting night for the Italy boss who is surely planning ahead for life at Stamford Bridge. Nainggolan played the entirety of Belgium's final warm-up game before the tournament in a 3-2 win over Norway, so it would be something of a surprise if he were to play some part this evening.
A good performance could make Conte all the more keen on the midfielder, even it is to the detriment of the side he is currently in charge of.
When is Zlatan not one of the players to watch? This evening he will look to spearhead an attack that could give Sweden the best possible start to the tournament when they face the Republic of Ireland.
With Ibrahimovic bringing his time with Paris Saint Germain to an end, it seems as though he is bound for the Premier League, with Manchester United the front runners for his signature - with Sky Sports reporting that his move to Old Trafford is on hold until after the European Championships.
Even at the age of 34 he is still the talisman for his side, although this could be his last major tournament, and if so he will want to make it one to remember.
