Graham Potter reveals what Chelsea must do after UCL win over Zagreb.

Denis Zakaria scored on his Chelsea debut as the Blues came from behind to beat Dinamo Zagreb at Stamford Bridge in the Champions League.

Graham Potter praised his Blues' Champions League victory over Dynamo Zagreb on Wednesday night, but the Chelsea manager was quick to insist that they must 'dust ourselves down for a big game [against Arsenal] on the weekend.'

The west London club had already wrapped up the top spot in Group E with a game to spare and were eager to return to winning ways after Saturday's 4-1 debacle against Brighton in the Premier League.

Chelsea did not start the match at Stamford Bridge with the right attitude as they fell behind in the sixth minute when Bruno Petkovic's header went in from close range in the 7th minute.

The hosts huffed and puffed after struggling to create much, but they eventually got their reward through a superb move that saw Jorginho's through ball get to Pierre-Emerick Aubameyang, and a backheel from the Gabonese striker found Raheem Sterling, who calmly created space before slotting the ball in.

The 18th-minute goal was Sterling's first goal for the club since August.

Then on-loan Juventus midfielder Zakaria wrapped up the win as he drove in a low shot in the 30th minute that went over the line despite a defender's attempt to clear.

Aubameyang nearly made it 3-1 when his powerful shot went against the crossbar, and Conor Gallagher's effort was denied towards the end of the match.

However, Potter said he was pleased with the result and not necessarily how they started the game.

'The quality was there'

"Really pleased," Potter told BT Sport. "Not the ideal start for us but the character was good and overall we played quite well. We attacked well, had some good chances and finished it off in a positive way.

"Whenever we have played Raheem Sterling we try to get him as high as we can. He has only ever needed to defend against the full-backs so it was a slight change in terms of the back four behind him but not too much change.

"The worry would be if you are not creating chances. Tonight we had a few we could have scored, obviously. But our intent was good, our play was good, and there is always ways to improve but the quality was there.

"We got the win, performance and the boys gave everything. We are a work in progress but with our Champions League campaign, we can be happy. We dust ourselves down for a big game on the weekend."

Potter 'was really impressed' with Denis Zakaria.

On match-winner Denis Zakaria, Potter lavished praise: "I thought he was really good. You can see what he brings, the quality he has and he played with enthusiasm. He had good discipline and got forward when he could. I was really impressed with him.

"He certainly did more than we asked which was to give us competition there. He did everything he could. He helped the team and scored - a great debut."
