Chelsea may have already returned to first team training at Cobham but as the World Cup reaches the zenith of the group stage there remains a great deal of Blues interest in the competition. On Thursday afternoon Croatia took on Belgium with both teams still needing to secure their place in the last-16.
There was not shortage of players who would be familiar to Chelsea on the pitch. Mateo Kovacic has starred for the Kockasti, while Romelu Lukaku, Eden Hazard and Thorgan Hazard were all on Roberto Martínez's bench. There were also some players who have been linked to Graham Potter's squad on show however.
Josko Gvardiol battled against Leandro Trossard in Qatar and given Chelsea's summer attempts to land the RB Leipzig star, his performance could remain of interest to the Blues' hierarchy. The 20-year-old has already impressed in the tournament and became the second player under 21 to start a World Cup match for Croatia, following in the footsteps of Kovacic.
