Thomas Mulller is pleased Bayern Munich teammate Serge Gnabry was never a prolific goalscorer with Arsenal.

The Germany international has blossomed since leaving the Gunners in 2016, first with Werder Bremen and now with Bayern.

Gnabry scored twice in Tuesday's 3-0 win over Chelsea at Stamford Bridge.

"I'm happy he is scoring so much in London now and not five years ago, because if that were the case he probably wouldn't be with us now!" Muller told Sky Sportin Germany.

Gnabry himself told BT Sport: "I certainly do [enjoy coming back to London]. I have a lot of friends here. A lot of them were in the stands tonight and I think they were giving me good power.

"Three goals should give us a lot of confidence. We need to be prepared for the second leg and we can't take it serious enough. It's still open but I think we have a good advantage.
