Different type of player. Carrick was very influential for us and allowed us to play a sitting player and a player who could get up and down. Zokora couldn't really do that and so we then 2 players who had t get up and down which left is exposed.
Zokora was a good player imo but just not what we needed at the time. Certainly good enough to get into many prem teams even now!
mg: you having a laugh, he was next to useless, constantly giving away free kicks in dangerous areas, appalling passing, appalling shooting, couldn,t head the ball, no composure and tackled on a football pitch like Boris Johnson, a truly poor quality midfielder.
