Russia vs Egypt to me looks like a game where it would benefit both to lure the other into taking the role of attacker for most of the game.
Egypt seem to struggle when they have to dictate the play in the games i've watched. Cuper has them set up as a low lying defensive side with Salah wreaking havoc on the counter once enough space has opened up.
Russia's defence is their biggest weakness, only RB Mario Fernandes is a good player. It wasn't good even full strength and with some CB injuries we've had to call back a completely washed up Ignashevich, a player now a liability against anyone fast, or more talented than relegation battling RPL teams. At left-back it'll likely be 34 year old Yuri Zhirkov who goes head to head with Salah, i rated Zhirkov highly...10 years ago before his knees fell apart. Even then, before all his injuries he was much better as a rampaging Brasilian style fullback rather than a great defender, nowadays he won't have the stamina or pace to keep up with Salah.
Russia will need to keep the lines close between midfield and a low defence and choose which countering opportunities to commit to wisely, the midfield has plenty of energetic players that can cover a lot of distance, no need for the defence to drift up high. The worry is being the home team and after such a good start, cherchesov will want to go to a more attacking set up. This defence isn't good enough to cover for that without giving up a number of chances.
