The 21-year-old winger was widely expected to move to Manchester, to either City or United, but has instead revealed that he will instead take up residence in west London
Although the transfer has yet to be made official, the 21-year-old winger confirmed on his Twitter profile on Monday that despite intense interest from Manchester City and Manchester United, he will be joining the Champions League winners this summer.
With talismanic forward Didier Drogba set to leave Chelsea imminently, Mavuba feels that the Blues have made a shrewd move in acquiring the services of Hazard to bolster their attacking options.
"It's good for him," the Lille skipper is quoted as saying by RMC. "I was a little aware [of it]. He deserves to go to a big club.
"Chelsea just won the Champions League. They need to rejuvenate their team and they have not made a mistake by taking Eden.
"He had many opportunities with the three top clubs and it changed a lot in his head. But if he chose Chelsea, it is because he has good reason to do so."
Hazard, who has been capped 27 times by his country, was recently named Ligue 1's player of the year.
