Former Chelsea coach Ray Wilkins has revealed the mistake made by Chelsea during the last summer transfer market.
Wilkins feels the Blues have been hit hard by the sale of midfielder Nemanja Matic to Manchester United.
Wilkins is convinced Chelsea is weaker when compared to last season.
“I don't think we are anywhere near as good as last year," Wilkins said.
“(Tiemoue) Bakayoko is no Matic, not yet anyway. Matic is just superb.
“I don't think we are anywhere near what we were last year."
Chelsea has lost two games in seven Premier League, their opening game against Burnley and last weekend defeat to Manchester City.
The Blues will return to Premier League action against Crystal Palace after the international break.
