Chelsea boss Frank Lampard has explained leaving out Callum Hudson-Odoi for their 0-0 draw with Tottenham on Sunday.

Hudson-Odoi has impressed since making his way back into the team in recent weeks, having scored the opening goal in Chelsea's 2-1 win over Rennes before making a cameo role in the win over Newcastle.

He looked set to feature in Sunday's derby but Lampard had to tell him that he would not be in the squad against Spurs, which ended in a goalless stalemate at Stamford Bridge.

While it was a blow for the 20-year-old, Lampard insists he is back in contention to face Sevilla in the Champions League on Wednesday evening.

"It was difficult to tell him that he wasn't in the Spurs squad as his attitude has been bang on," Lampard said in his press conference on Tuesday.

"He was bright against Rennes and Newcastle. He is getting better and is back in contention and I want him to keep that going. I want him to stay positive.

"I am aware of Callum and where he is at, he took it well but it wasn't and easy conversation. I am not worried about the noise around it, I just have to pick the right squad. I have to work with him positively.

"I can relate to it because we all have steps on the ladder. He got into the team and there was a lot of talk around him and he got a bad injury.

"Now time and work have shown that he's back and then you have to appreciate he is developing.

"I have to see the bigger picture and he is hopefully going to have hundreds of games ahead of him. We have a big squad, it has to be a strength and not a weakness."
