Chelsea have completely turned around their defensive record with another clean sheet in the 3-0 win over Rennes.

The Champions League victory on Wednesday night means the Blues have not conceded in five straight matches, the first time they have done that in ten years.

Edouard Mendy has had a sensational start to life in west London, while Thiago Silva and Kurt Zouma have formed an excellent partnership at centre-back.

With Ben Chilwell and Reece James looking solid in the full-back positions, Frank Lampard's defensive side are really starting to come together.

One of Chelsea's big weaknesses last season was their defending from set-pieces, with it looking like they would concede every time the ball was put into the box.

But during this campaign, apart from the draw with West Brom, it has looked a very different situation.

A key reason for that has been the work of new coach Anthony Barry, who came into the club in the summer from Wigan Athletic.

The new coach had to move position to see past Frank Lampard, Rennes head coach and fourth official Tobias Stieler.

When he did, he was as loud as anyone, calling players into the right positions and making sure each one was doing their job.

In the second half, he was a clear voice in shouting towards Zouma to make sure the centre-back was in the right place from a free-kick, also getting Hakim Ziyech to mark Steven Nzonzi.

When a new substitute came on, it was Barry who spoke to them about where they would be positioned when defending set-pieces.

Lampard has a lot of faith in his coaches, Jody Morris, Joe Edwards, Chris Jones and Barry, who have formed a tight unit.

"He's an exciting young coach and someone I've known for a while. I believe he will be a strong addition to the team," Lampard said when the coach arrived in the summer.

And he looks like he has certainly had a good influence on Chelsea's set-piece woes from last season.
