this is my opinion.. i prefer essien to play at ashley cole place against barca simply because he have more experience than ivanovic.

but, the main problem is that wingers from good teams usually change their flanks and the love torturing opposition defender. so, even with essien at left back, i dont think messi will confront him face to face since ivanovic is the obvious less-expeience player. if eto'o and henry join also, sure can be a nightmare for ivanovic.

however, there will always be a miracle in football. hopefully we can get through ^^V
