England Training - EURO 2016
It could be a significant game in both Groups B and C at Euro 2016 today - with the game undoubtedly catching the most attention is the early kick-off when England meet Wales in Lens.
Wales won their opening game against Slovakia - and there may be a little more pressure on the shoulder of the Three Lions following Slovakia's win over Russia in Lille yesterday to leapfrog them in the group ahead of kick-off.
Ukraine take on Northern Ireland in Group C with the two sides looking for their first points of the campaign. Northern Ireland lost out to Poland in their opener while Ukraine were beaten by Germany.
It is a crucial day for those groups - and the actions of one player could decide the outcome of these matches - so here's three players to look out for in today's encounters.
Wales Training - EURO 2016
It's safe to say there has been a lot of talk from the Wales and Real Madrid star ahead of their crucial clash with England - whether he has got under the skin of their rivals remains to be seen. It's time to see whether he can back those words up with actions and build on his goal in the opening game win over Slovakia.

Northern Ireland failed to register a single shot on target in their first game against Poland, as there was a lot of emphasis on remaining solid and trying to get a point. But when they system was changed after going a goal behind, it was clear the Southampton star is one of the side's best players - when he got on the ball he looked capable of unlocking a defence and the Northern Irish looked a threat. They are going to have to do something going forward against Ukraine to have any chance of getting through to the knock-out rounds - and one would expect their captain to be at the centre of it all.
Germany Training - EURO 2016
He was given something of a thankless task in Germany's first game against Ukraine by playing as the main striker. He found it pretty difficult to get into the game and have a real impact - so it will be interesting to see what kind of role he is given when they meet Poland tonight.
There is still interest in him from Liverpool, according to the Liverpool Echo, as they look to strengthen their options in the final third. Gotze would probably like to play in a role off the striker or out wide instead of leading the line himself - but in a game that is likely to be keenly fought against Poland, he would want to have more of an impact tonight.
