Chelsea playmaker Deco is a big fan of manager Carlo Ancelotti's diamond formation. Deco made no secret of the fact that he was open to leaving Stamford Bridge in the summer but is now enjoying his football once more.
"We know that Carlo played this system in Milan for many years and here I think we have good players to play in this system," he said.
"We have great midfield players and this system gives the option to play well because normally all the time we have one more player in midfield than the opposition.
"Sometimes it is hard to defend because if the other team has a good full-back that attacks much, the midfielder needs to go close him because we don't have a winger to help.
"But all systems have disadvantages. I think to play this way is fantastic."
The 32-year-old also revealed that his favoured position would be to play behind the strikers at the tip of the diamond, a position currently occupied by Frank Lampard.
"Of course when you play behind the strikers you have to help the striker (attack), but you also have to help your team control the game because if you don't help with the distance between the midfield and the strikers, the connection isn't there," he added.
"Playing in this position you can lose the ball. If you are playing in front of the defence it is the danger zone if you lose the ball near the penalty box of the opposition it is okay, no problem, you can't take more risks here."
