#4 Ivan Rakitic - Croatia
Lionel Messi's Barcelona teammate, Ivan Rakitic will not be as happy to share the field with him this time around. Barcelona fans' consensus on Rakitic is divisive for the most part, but with Croatia, he is as good as they come.
With the quality around him, Rakitic becomes even more attacking than he is with Barcelona and has a knack of popping up in the opposition box. Further, he is not the kind of player that will shy away from any challenge whatsoever.
One of those players who can switch seamlessly between offence and defence depending upon what the manager asks of them, Rakitic is likely to play a bit more defensive than Luka Modric.
In the game against Nigeria, he was employed in a more defensive role, but against Argentina, there is a chance that Croatia will employ a 4-3-3 formation to take advantage of Argentina's defence.
