Deco has urged Chelsea teammates not to panic after last week’s defeat to Tottenham.
The 32 year-old Portugal international midfielder has the experience of winning titles with Barcelona and Porto.
Deco told reporters that : “First thing we need, we need to know that we are first,”.
He also added that : “The last three games will be difficult and of course there is pressure in our minds because we need to win our games if Man U win theirs.
“It is a war, and we need to be prepared but, if you said on the first day of the Premier League in August we would be one point clear with three games to go, two at home and one game away, we would all say okay, I’ll sign!
“This is okay, it could be better if we won or Man U lost, okay, but it didn’t happen, and our moment is this – we have three games, two at home and one away – we need to play well and be together.”
