Vincent Kompany paid tribute to "underrated" Serge Gnabry following his brace in Bayern Munich's 4-0 win over Union Berlin.

Bayern maintained their nine-point lead at the Bundesliga summit with a commanding victory at the Allianz Arena, where Michael Olise and Harry Kane were also on target.

Gnabry, who earlier this year signed a new deal to keep him with the Bavarian giants until June 2028, scored in each half to take his Bundesliga tally for the season to eight.

And Kompany heaped praise on the winger.

"He's just as good as our other attackers," he told reporters during his post-match press conference. "Honestly, I always like to talk about Serge positively, even more than the others.

"He was often injured and sidelined, and that might have hurt his consistency a little bit. But overall, he's always performed for us this season, centrally, on the left and sometimes on the right. He's a very important player for us, on the pitch and in the dressing room.

"[His form] doesn't surprise me at all, but it always pleases me. Of all our lads, Serge is perhaps the one whose talent is most underrated, because he's sometimes injured and out of action. That's why I'm always delighted when Serge shows just how good he is."

Kane, who scored his 31st Bundesliga goal of the season, also saluted his team-mate's performance.

"He was fantastic. I thought he brought a lot of energy," the England captain added. 

"One-on-one, he was so dangerous. He gets into the dangerous areas and has a great finish on him. He's one of the best finishers I've played with. If you give him opportunities, he's going to score goals.

"It was probably one of our better performances of the season. From start to finish, the way we moved the ball, the way we got on second balls, kept the rhythm of the game high and intense.

"Our quality shone through towards the back end of the first half, then carried on into the second half. So overall, just a really good win."
