The Blues won last season’s Champions League, but Argentine midfielder Aimar says times have changed.
“Of course, Chelsea are a big club, but this is not the same team that won the Champions League a year ago,” said the 33-year-old. “This team got knocked out at the group stages. They have not been convincing in Europe or in the Premier League.
“Since they have inherited a wealthy owner, this is probably the weakest Chelsea team there has been.
“And it is a team that is not behind the coach. We can take advantage of the fact they are not at their best and not playing as a team.
“Chelsea lost two great players in Didier Drogba and Michael Essien.
“It is amazing how much a team can change in 12 months, but that is football,” Aimar added.
