Serge Gnabry turned North London red with a white-hot display against Tottenham Hotspur, and then fired a warning to the rest of Europe that Bayern Munich are serious about winning the Champions League.

The former Arsenal winger almost single-handedly obliterated Spurs with four goals in Bayern's 7-2 victory at the Tottenham Hotspur Stadium, with Robert Lewandoski and Joshua Kimmich also on target

The victory - the time Spurs had ever conceded seven goals at home in Europe's premier competition - puts Bayern at the top of Group B with six points and 10 goals scored from two matches..

"I think [the other teams] know we are not stopping. After the 3-1 or 4-2 we could have stopped but we wanted more," Gnabry, whose career never took off at Arsenal before leaving the Gunners three years ago, said..

"I think it's a big message for everyone else."

A player not considered good enough for West Bromwich Albion on loan has thrived since returning home, first with Werder Bremen and then with Bayern where he is now a full German international.

His performance on Tuesday might make Arsenal fans wonder quite why he was given so few opportunities.

"I think the last time I scored four goals was when I was a child!" the 24-year-old said.

"I'm very happy with my performance of course and glad I could help the team to such a big win. To score seven goals away at Tottenham, I don't think this happens a lot!

"It was a great night and we're in a good place now in the Champions League."

After a relatively slow start to the season, Bayern have picked up the pace and are now top of the Bundesliga and with back-to-back matches to come in the Champions League against Olympiakos they look set for the knockout stages.

"I said today was one where we would see where we are," Gnabry said. "Seven goals doesn't happen often but we have to keep our feet on the ground. If we do that then performances like that can come more often."

As horrifying as the scoreline looks, Spurs manager Mauricio Pochettino could point to individual errors for the concession of the goals rather than Bayern dominating proceedings.

Right-back Serge Aurier was culpable for at least three of the goals, and was given a torrid time by the surrging runs of Gnabry.

Tottenham have been inconsistent this season but when Son Heung-min fired them deservedly ahead after 12 minutes it appeared the spark that has been missing had returned.

Even when Bayern equalised through Kimmich's sublime strike, shortly after Tottenham recovered to look the better side against the five-time champions.

Then the ceiling fell in.

Lewandowski's superb effort seconds before the interval knocked the stuffing out of Tottenham and Gnabry's second-half hat-trick and another masterful strike by Lewandowski inflicted Tottenham's worst home defeat in Europe.

That it happened on his watch was especially galling for the proud Pochettino and will add to the feeling that all is not well at Tottenham, just four months after they contested the Champions League final for the first time.

"I feel so bad because when you concede seven it's so tough, but you need to face this type of situation," Pochettino told reporters. "You need to show your quality like a man first, then face like a professional."

The result leaves Spurs with one point from their first two games, one more than they had at the same stage last season after defeats by Inter Milan and Barcelona.

"It's a tough situation, but you have to face it," said Pochettino. "We have to stay together and help each other. The best medicine is to be all together."
