He's a player with ball winning capabilities and a wide range of passing, "technically brilliant" or even "fantastic passer" is taking it a tad too far.
Yes i'm aware he played that role for Croatia, but Rosicky played that role for Czech Republic as well, still he failed miserably and was obviously lightweight when Arsene played him as CM.
Isn't Modric a bit lightweight to play as a central midfielder in a classic 4-4-2? i think playing behind the strikers like Redknapp is playing him now, is his best position.
