Serge Gnabry has done pretty well for a bloke Tony Pulis once decided wasn’t good enough for West Brom.

The former Arsenal academy star, also deemed surplus to requirements at the Emirates, showed once again how wrong the Gunners were to sell him with a masterclass against Tottenham during Bayern Munich’s stunning 7-2 victory in the Champions League.

Gnabry bagged four sensational second-half goals to inflict an embarrassing defeat on Spurs during the group stage clash in north London, dispelling any doubts, if any remained, as to whether he would’ve cut it in the Premier League.

To make matters worse, Arsenal only got a measly £5million for him when they sold him to Werder Bremen in 2015.

The 24-year-old has since gone on to win Bayern Munich’s 2019 Player of the Year award and become a regular international for Germany.

He’s come a long way since his loan spell at the Hawthorns during the 2015/16 season, when Pulis handed him just 12 minutes of top-flight football.

And with Arsenal’s club-record, £72million signing Nicolas Pepe struggling for form at the beginning of the season, Gnabry’s performance against the Gunners’ fierce rivals will have certainly rubbed salt into the wounds.

After Joshua Kimmich cancelled out Heung-min Son’s opener, Bayern took the lead on the stroke of half-time thanks to a superb finish from Robert Lewandowski.

The Poland striker picked up the loose ball at the edge of the area and swivelled to fire into the bottom corner.

Bayern extended their advantage eight minutes after the break as Gnabry broke at pace and fired into the bottom corner.

And Spurs’ misery was compounded as Gnabry struck again two minutes later, capitalising after Harry Winks lost possession.

Mauricio Pochettino’s men were handed a lifeline as the referee pointed to the penalty spot for a foul on Danny Rose, with Harry Kane reducing the deficit to 4-2 on the hour mark.

Any hopes of a comeback were dashed when Gnabry sealed his hat-trick in the 83rd minute after racing beyond the Spurs defence and slotting past Hugo Lloris from 15 yards.

There was still time for Lewandowski to side-foot home a sixth for the German giants and Gnabry was able to add his fourth – and a seventh for Bayern – in the 88th minute.
