Frank Lampard rues Chelsea's wastefulness in front of goal in Arsenal draw: 'When those chances come, we have to take them'

Frank Lampard has said his Chelsea players have thrown away 10 points this season through their lack of clinical finishing in front of goal as his team were once again frustrated at home.

Chelsea’s need for a striker in the January transfer window was underlined during their dramatic draw with 10-man Arsenal, when Lampard’s side dominated but once again failed to convert their superiority into a victory.

Lampard is desperate to add more firepower to his attack this month and the Chelsea head coach will now be worrying about the fitness of top scorer Tammy Abraham after the striker limped down the tunnel at the end of the match.

“We’re in fourth position, that’s seen as pretty good but we know there should be another ten points on the board at least based on performance,” said Lampard. “All of us need to look at those finer details.

“We know the story here at home. Teams with 11 have defended like that against us and given us problems. Fair play to Arsenal, with 10 it’s understandable and I thought they defended their box pretty well.

“But we have to look at ourselves and say that again it is a story of creating a lot but at this level, when those chances are coming, we need to take them more.

“I know that the expected goals - I don’t like too many stats on expected goals - but we are bottom of the league at home in taking them [chances] and we are second to Liverpool in creating them. So that is just two ends of the scale that shows where we are at.”

Mikel Arteta, the Arsenal head coach, hailed the spirit of his players after their remarkably gritty response to losing David Luiz to a red card after a Shkodran Mustafi mistake had played his team into trouble.

Goals from teenage forward Gabriel Martinelli and returning full-back Hector Bellerin pulled them back into the game, twice, after Chelsea had taken the lead.

“The spirit, character, fight and leadership were there,” said Arteta. “You have to really stand up. When someone makes a mistake and someone has to take a red card for him, it can happen. What has to happen is you have to stand up for him and every single player did that.

“We’re still a long way from many things we have to improve but in terms of this spirit , this will give us the platform of everything we want to build together. Without this you can’t compete to any level.”

Martinelli, 18, has now scored 10 goals in his first season in European football, including three in his last five Premier League starts.

“To play in this stadium the way he has, with ten men and against Azpilicueta, one of the best defenders in the league, you need courage and energy,” said Arteta.
