Chelsea boss Andre Villas-Boas admits he has concerns over their defence after defeat to Liverpool.

Glen Johnson's 87th-minute strike snatched Liverpool's 2-1 win - and sent Villas-Boas crashing to his fourth defeat in his first 12 games as a Premier League boss.

The Portuguese coach admitted: "The amount of goals we are conceding is something that worries me.

"So we have to analyse what will make us better in terms of defensive organisation.

"When you are conceding goals in situations like this and being so low in the league, you focus on the details that you have to get right.

"That's exactly what we're doing and we know where we have to improve. We don't concede a lot of opportunities but our opponents are being more efficient than us.

"But I still trust our defenders because we have immense talent at our disposal and we all believe we will get it right."
