Frank Lampard has admitted his side weren't good enough during their 1-0 defeat to Everton, and feels it was a reality check for those who have said Chelsea have the best squad in the division and are Premier League title favourites.
The Blues fell behind to a Gylfi Sigurdsson penalty at Goodison Park on Saturday and were unable to fashion a response.
Lampard says his side did not stand up to the physical challenge posed by Everton, and feels lessons will be learned from the performance.
