Speaking ahead of Tuesday's match in St Petersburg, Cuper again put himself at odds with his federation by insisting final medical checks must be carried out, although he expects Salah to face hosts buoyed by a 5-0 thrashing of Saudi Arabia.
Salah broke the record for most goals scored in a single 38-game Premier League season last campaign after netting 32, beating Alan Shearer, Cristiano Ronaldo and Luis Suarez's previous record of 31. "We do not play against a single player, but we know how we are going to stop him".

In fact, Russian Federation have failed to win their second game at the last five World Cups - they last did it as the USSR, beating New Zealand 3-0 in 1982.
"I am absolutely buzzing, everyone on the staff is". Dries Mertens opened the scoring with a stunning volley and Romelu Lukaku bagged a second-half brace in Sochi. "It is nearly a mental blow for one team and it gives you a lot of breathing space for your first game in the tournament".
