Chelsea boss Andre Villas-Boas concedes finishing has become a problem for them this season.

Villas-Boas believes his side - who had won back-to-back games heading into their draw at Norwich City - must be more clinical.

"We are in the top three teams for creating chances, but the efficiency was not there and this represents where we are in the table," the Chelsea manager said.

"We have to find the consistency for us to get on a winning run which can make this title challenge a little bit more, that is the reality.

"It is not going to be a lack of ambition or motivation. There is always motivation when you play for a top club."
