One Everton star, a former Manchester United player and one linked with a move to Old Trafford could all have a big say.
The line-up for the last-16 of Euro 2016 will be completed today as fixtures in Group E and F come to an end. Group F's games take place first, kicking off at 17:00 with Hungary taking on Portugal in Lyon and Iceland taking on Austria at the Stade de France.
Hungary have already made it through to the next round of the competition, as they are top of the group on four points from their opening two games, with Iceland and Portugal both on two points, and Austria on one point, so there is all to play for going into this final round.
Italy have already qualified from the group in top spot having won two out of two so far while Belgium sit second on three points. Both Ireland and Sweden have one point each and need a win to keep their Euro 2016 hopes alive.
Here are three players who could be key in today's encounters:
It is safe to say it has not been his tournament so far. The Real Madrid star failed to find the net in the opener against Iceland, while he missed a penalty and had a goal ruled off in the subsequent clash against Austria.
With Portugal on just the two points, the pressure is really on their star man and captain to try to find his form in order to help the side top the group with a victory over Hungary.
After a disappointing first game against Italy, the Everton forward shone for Belgium in their 3-0 win over Ireland in the second match, scoring two goals to put them in prime position to finish runners-up in Group E.
If Belgium are to succeed in this tournament then they are going to need their centre-forward firing on all cylinders. They have a huge game tonight against Sweden, where avoiding defeat will be enough to secure second spot.
The Swedish talisman announced he would be retiring from international football after the tournament, but some would joke that given by his performances in the opening couple of games that he has already done that.
He has been pretty anonymous and ineffective, and they need him to turn in a pretty good performance tonight against Belgium so his international career can be prolonged for at least one more game.
