yea carlos gave us, speed, creative flair and imagination in midfeild and upfront, fergie gives us the tactics, defensive aspect and experience of how to win games and hold out etc you can say carlos in corporated his attacking style into fergie tactics to give it a boost!!
it really was a perfect partnership, fergie knew that, which is why he came back to us and then we dominated in the league and in europe, with him gone that attacking threat has gone and style of play is predictable and boring, that i don't think is fergie fault but phelen if im being honest.
carlos and fergie was like a NFL partnership, one on atacking the other on defensive, it was perfect when them two were at the helm!!
although i hope carlos doesn't get sack of manager of portugal i hope by the end of the world cup he comes back to us for fergie's last years and send the great man himself leaving on a high coz he deserves it!!
