Chelsea legend Gianfranco Zola is impressed by their summer business.Chelsea, boosted by the signings of Spain duo Cesc Fabregas and Diego Costa, are the early favourites for the Barclays Premier League after winning their opening three games.
Zola said: "I think it was very clever the way they used their money. They have a strong team, in every position they are very good.
"The quality of the football has been made better and I believe that Fabregas has a lot to do with that.
"Chelsea look like they will be one of the teams to beat - but the Premier League is long and the tough moments will come."
