England and Belgium wrap up Group G on Thursday, with both sides already assured of a place in the last 16 but first and second place still to be decided.
Here Press Association Sport looks at the pressing issues ahead of the fixture.
Bragging rights or best route?
As soon as it became clear the runners-up spot might offer a gentler path of progression in the tournament, questions began to surface as to whether either side would really want to win in Kaliningrad. Although there is valid logic to that line of enquiry it ignores the fact that the squads of England and Belgium contain a total of 35 Premier League players, plus four more who have experience of the division. That adds up to a lot of established rivalry, club friendships and chances for one-upmanship and they will not be passed up lightly. The likes of Chelsea, Manchester City, Manchester United and Tottenham are all represented in both dressing rooms and the match will have been discussed at training for months.
Changing of the guard
The likelihood that both teams will indulge in significant rotation has been well-trailed, with some players likely to be wrapped in cotton wool, others rested for conditioning reasons and no risks likely to be taken with those on yellow cards. The real question is how high the total number of changes will reach. If it approaches FA Cup third round territory, what looked like one of the group stage’s most interesting contests could lose some of its A-list lustre.
Can Kane keep it up?
With five goals in the first two games, Harry Kane has truly arrived on the international stage and has made it perfectly clear he wants to continue riding his hot streak against Belgium. Gareth Southgate’s instincts might be more cautious as he eyes the knockout stage but it looks increasingly likely his captain’s hunger will win the day. He is just one away from Gary Lineker’s six-goal salvo at Italia 90 and will want as many chances as possible to overhaul it.
Vincent Kompany’s physical frailties cost him a place at Euro 2016 and briefly looked like denying him a place in Russia too. He has been managing a groin problem in the early stages of the tournament but has been passed as ‘medically fit’ for the Group G decider. If the Manchester City captain is to play any part in the business end of the competition he probably needs to prove his sharpness now. For him, more than most, this could be a crucial 90 minutes.
Throwing cautions to the wind
If the teams are level pegging as the game winds towards its climax, do not be surprised if attention turns to the referee. With the teams tied on points, goal difference and goals scored, the group winners would be determined by disciplinary points. England are currently marginally ahead on that metric and it could be telling if either side produce a slew of rash or cynical challenges late on. As well as the calibre of likely opposition, Belgium are said to be happier with the travel arrangements attached to second place and a couple of yellow cards could be enough to secure it.
