4. Dejan Lovren (Croatia)
Lovren will need to be solid at the back for Croatia if they are to make any sort of impact in Russia. Croatia have a pretty decent squad and boast one of the best midfields in the tournament consisting of Luka Modric (Real Madrid), Ivan Rakitic (Barcelona), Marcelo Brozovic (Inter) and Mateo Kovacic (Real Madrid).
Croatia however, find themselves in one of, if not the toughest group, having to battle Argentina, Nigeria and Iceland. The Croats should fancy themselves to make it out of the group but should aim to do so as Group winners. This should be tough in a group featuring a Messi-led Argentina but a second place finish means a clash against potential Group C winners France.
Should Lovren and co win the group, however, a place in the quarterfinals could be a real possibility but the semifinals would be a step too far.
