Frank Lampard refuses to abandon his principles as he looks to navigate Chelsea out of a barren spell.

A run of three defeats and a draw from their last five matches has seen the Blues lose ground in the Premier League title race, although their previous 17-game unbeaten sequence keeps them firmly in contention.

Manchester City visit Stamford Bridge on Sunday and Lampard will continue to self-reflect in a bid to engineer a revival.

"Every player goes through tough times in front of goal. The beauty is that Timo's been getting chances and that's definitely a positive," Lampard said.

"I found work on the training ground was the only way to turn it around – that repetition of finishing, which Timo is doing now.

"When you work like that it's a matter of time because his natural attributes will get him in front of goal and away from defenders.

"If his confidence goes down after missing a couple, that's only natural. It's my job to help him with his confidence and push him in a positive direction. Then the goals will come.

"He's sharp, he can finish. And sometimes the onus is on us to get him the ball in the right areas."
