Gronzy:Mohamed Salah, a star attraction ahead of football's 2018 World Cup in Russian Federation, has made headlines for a smiling photo with Ramzan Kadyrov, strongman of Chechnya where his Egypt team have set up camp.

Salah moved to Liverpool FC in a £39m deal from Serie A giants AS Roma in a 2017 summer transfer window.
