Frank Lampard has warned his gaffe-prone defenders Manchester United’s red-hot attack is a “different animal” to the Norwich frontline they shut out.
Chelsea began the season with a 4-0 defeat at Old Trafford.
He said: “We will have to be very much on top of ourselves when it comes to the quality of opposition.
“No matter what, they can hurt any defence or any team with the individual quality they have.
“It was good to get a clean sheet against Norwich.
“This will be a different animal and we will have to defend very well.”
