Chelsea assistant coach Gianfranco Zola says fans shouldn't forget Jody Morris when Derby visit for their Carabao Cup clash.

Morris, a former Blues player and outstanding youth coach, acts as No2 to Frank Lampard at Derby.

Zola said: "I don't want to forget Jody. I don't know Jody as a coach because I didn't come across him, but everybody at the club here speaks very highly of his coaching ability. From what I have seen, the way Derby plays, they are really doing a great job together.

"We are going to study them. We know their strengths and we are going to be working on that. We certainly respect their value because we know they are a very good team.

"They have a lot of good players - for example Mason Mount who belongs to Chelsea, also [Tom] Lawrence, [Harry] Wilson, [David] Nugent. We know they have a lot of quality up front. We will have to play the game with a lot of respect for them, otherwise there will be trouble."
