As a Chelsea and West Ham fan Chelsea should never had sold Arjen Robben and for West Ham they should have never let Scott Parker go.

Ronaldo to Madrid!

Kaka

ROBBEN 

TO MADRID ....i think he could have done wonders in chelsea if stayed .

Silva

Eto'o + 50 Million for Ibrahimovic! oh god..

barca sell yaya,milan sell pirlo,arsenal sell fabregas....and that made big efect to those clubs.

schewtschenko should never have been sold to chelsea

Beckham, Ruud & Ronaldo should have never been sold to Madrid.

Henry

we should of never sold jaap stam...class defender 

Lucio from Bayern to Inter , till now since lucio left.bayern didnt have a strong and loyal center back as lucio , and ballack , selling ballack is like selling scwheinsteiger now which me and any bayern munich fan cant think of it even .

Every player going to madrid... Kaka Ronaldo Khedira SAHIN Coentrao

Hargreaves, one of my favorite players who used to play for united, they should have gave him another chance.

^ Hargo's Knees are a wreck man. We had no other choice. Man when Saha left horrible day. 

I think Torres should've never been sold to Chelsea,even he has won titles with Chelsea but he didn't have much impact....

omartawfik totally agree, Bayern should've never let Lucio go. Lucio was the heart of Bayern's defense, a great player who really dedicated himself to the club.. what a shame van Gaal didn't even give him a chance

We should have never sold Raul.

Eto'o.. he was a beast at Inter... or Ibrahimovic.. but Ibra was very aggresive at Inter he did got alot of red cards.. and we dont need these kind of players...

And i think Mario Gomez should have been never sold to Bayern Munich :O i cant belive he cant dribble or pass only finish and he even missed that in champions leauge final , if we had dzeko at that final ...
