I have not seen the game as yet but judging from the reports i see here,it should tell us one thing,big money alone is not the answer.
When you have quality Coaches with quality players what separates them is quality coaching and tactics,in this game it's not about like and don't like like,watch the game with an open mind and you will see why teams win or lose certain games.
On paper Chelsea suppose to dominate the EPL but there will always be games they going to struggle because of the tactics the other team uses,look at Arsenal,Man Utd,Liverpool etc these teams have lost players,some through injury and still produces quality Football with who ever they got.
A part of the game that we as supporters will never know is why Coaches make the decisions they make,selections,substitutions etc in a lot of cases it's made on who they playing against,Arsenal leave Henry on the bench Man Utd leave Rudd on the bench and we say these coaches mad,the bottom line is Coaches do what they have to do gain results sometimes it work or does not work,that's reality.
