Aimar described the current Blues squad as the worst since Roman Abramovich bought the club 10 years ago.
The Argentine expressed his bemusement at the fact that neither John Terry nor Frank Lampard are now considered regular starters while he also claimed that the Chelsea squad are not behind their interim manager Rafael Benitez.
"In my opinion the strongest team make the Europa League final. Chelsea is an excellent team and they will finish third in the Premier League this year. They have quality."
