Bayern Munich winger Serge Gnabry may well have aggravated Tottenham fans even more after his stunning four-goal showing on Tuesday by posting 'NORTH LONDON IS RED!!!' on Twitter.

Gnabry's performance was a lesson in finishing as he contributed to a 7-2 thrashing of Spurs at the Tottenham Hotspur Stadium in the Champions League.

The 24-year-old, who played at Arsenal for four years, deepened the wound with the boastful tweet less than an hour after the game finished.

After a Robert Lewandowski strike in first-half injury-time sent Bayern in 2-1 up at the break, Gnabry took centre stage with a quick-fire double to extend Bayern's lead.

The German international claimed his hat-trick on 83 minutes, before adding a fourth - and Bayern's seventh - five minutes later.

The winger has now scored five goals in eight appearances in all competitions for the Bundesliga champions this season.

Former Bayern midfielder Owen Hargreaves said Gnabry is playing at a level where he 'blows everyone away'.

Gnabry made his senior Germany debut in 2016 and has scored nine goals in 10 appearances

Gnabry played for Tottenham's great north London rivals, Arsenal, between 2012-2016

Speaking on BT Sport, Hargreaves said: 'The German manager [Joachim Low] said the other day he was the first name on the team-sheet.

'That is the level he played at for the last season and we saw that tonight. He blew everyone away.

'He just runs at defenders, leaves them for dead, and the finishing is exquisite.'

Ex-Spurs striker Peter Crouch also highlighted the performance of Gnabry, as well as fellow wide-man Kingsley Coman - the pair were up against Tottenham full-backs Serge Aurier and Danny Rose.

Crouch said: 'Right from the beginning the full-backs were going to have a long evening unless they doubled up.

On the other flank Kingsley Coman was also a constant threat against Tottenham's Danny Rose

'Coman and Gnabry were running riot. They were for the full 90 minutes. I don’t know why it wasn’t spotted earlier and nipped in the bud.'

Rio Ferdinand, a Champions League winner with Manchester United in 2008, referred to Bayern's experience and deadly finishing.

'Serge Gnabry showed Arsenal what they let go,' Ferdinand told BT Sport.

'Listen we talked about Bayern Munich being a team in transition, they are a team ready and able.

'Wing play of the highest order from their two young wide players. Their undoing was the goal just before half time that was a pivotal moment on the match.

Rio Ferdinand, Peter Crouch and Owen Hargreaves were full of praise for Bayern's display

Arsenal's Hector Bellerin, who played with Gnabry at the Emirates, tweeted his thoughts

'I loved it, I love seeing good football, I was in here jumping and screaming and enjoying what was on show!

'Mainly the wide players, I love seeing wide players who can do unbelievable movement to get on the ball, move defenders then play and run. When they got in they were clinical.

'From then on this Bayern team looked like a team with experience, ability to control the tempo of the gam - they scored at will today.'

However, Ferdinand was less glowing about Tottenham's defending and ball retention.

'As a defender I feel like you are cheating yourself if you dive in,' Ferdinand stated.

Former defender Ferdinand was unimpressed by Aurier continually diving into tackles

'Aurier is quick enough to run back if he makes a mistake but he dives in and makes up Gnabry’s mind.

'How many mistakes did Tottenham make in possession? Bayern were there to pounce. It was almost comical.'

The result leaves Bayern top of Group B on six points from two games, with Spurs lying in third on one point, behind Red Star Belgrade on three points in second - Olympiacos are in fourth.
