I'd field this thank you very much.
That midfield will be killed
Rakitic will be played in a position he is least comfortable and his rightful position will be taken by a lesser able player
Rakitic is poorer at defending as compared to busquets and xavi is poorer than rakitic
And your team has only two/three players who can defend set pieces, another trouble waiting to happen
Xavi and iniesta cant defend as we know, they will be killed alive by madrid's counters as they have been killed so many times before
You are taking it for granted that Madrid are in poor foorm but both teams bring their A game to a game as big as classico. The last classico came at a time when we were in great form and hadnt conceded a goal and then baaam
Masche has flopped in all the big games he has played as a CB so playing him there is another big No
Edit: i mistook this for el classico but still the same arguments apply
