Manager Nigel Pearson warned that runaway Sky Bet Championship leaders Leicester City cannot afford to lose focus in the final 13 games of the season.

After beating Charlton 3-0 at the King Power Stadium, City are eight points clear of Burnley in second place and 13 points ahead of Derby who are third.

Leicester boss Pearson said: "There could still be set-backs , we deserve to be there. But we have got 13 more games to go and 39 points to play for.

"It would be nice to do it ourselves and I think that the key to this season is that we we have always spoken about what we do ourselves rather than what other people do.

"We will try to keep that going but we may still get set-backs. But I would rather be in the position we are in than third and trying to ease a way into the top two. The dangers to us are a loss of form and people's desire to point to historical events like last season (when City had a bad run to drop out of the top two)

"The big danger is that you get side-tracked into losing focus on what we are able to do ourselves.

"I think we have a better squad this season and have a good balance within the squad. The focus of the players is very much on being successful. We have put ourselves into a good position and with 13 games to go. You have got to live in the moment and we want to try to win every game we play."

Addicks boss Chris Powell said he believed they had been beaten by the "champions elect" but claimed the first goal was offside.

He said: "It has been a tough week for us and I suppose coming to the league leaders was not the fixture we would have wanted.

"They are a very good side and we have possibly played against the champions elect if they carry on the way they are playing. But I was disappointed about the first goal that was clearly offside and if we could have gone into half-time level that would have helped.

"But they scored an early goal in the second half and that had their tails up. Then really it was a question of making sure we came away from here with not a massive defeat and I suppose I've got to be happy with 3-0.

"We didn't have an eye on next Sunday's FA Cup tie against Sheffield United. We cannot afford to do that. We will focus on that this coming week. The target is to progress as far as we can in the cup and stay in the Championship."
