I thought about this for quite sometime and I have to say, I nearly picked Drogba (it's time to make way for Lukaku). Nearly. My number 1 choice is:
Claude Makélélé:
Hailed by many as one of the greatest defensive midfielders ever, Makelele was by far our best defensive midfielder ever. At the time being Chelsea only have Mikel, Essien, and Ake to be their defensive midfielders. Mikel is great at defending but is nowhere near as good at passing as Makelele was. Actually, Makelele is also MUCH better than Mikel in defending too. Essien is a shadow of himself. And Ake is too young to be a starting defensive midfielder. In fact, Chelsea's DM role has never been the same since Makelele left. But that's not it. Makelele was the best defensive midfielder of last decade. He was so great at his role that they named his role "The Makelele Role". With the Chelsea squad already filled in most areas, but since '08 Chelsea have been in need for a defensive midfielder like Makelele.
Who would it be?
The rules:
1) You cannot pick players you already have who are old and say you want him in his prime. It should be an ex-player
2) Its based on your current squad. Think smart. So despite me wanting to see Zola back in his old days playing with this new young team, I already know that we have the likes of Mata, Hazard and Oscar who could compete with him (and probably win).
3) The player you pick will have the same age he was when he first joined your club.
4) Try to pick one player. I understand it will be difficult but try to make a decision. If you cannot then its okay.
Also, it would be great to add the reason why. You dont have to but it would be nice to know why you chose the player you picked.
