Serge Gnabry played only 135 minutes while on loan for West Brom - he made two League Cup starts and one 12-minute Premier League cameo

"Serge has come here to play games but he just hasn't been at that level to play the games," said West Brom manager Tony Pulis a couple of months before Serge Gnabry returned to Arsenal in January 2016.

Six months later the Gunners sold him to Werder Bremen for less than £5m.

On Tuesday, Gnabry became the first player to score four goals in the second half of a Champions League game as Bayern Munich destroyed Tottenham 7-2.

It's safe to say the 24-year-old winger, who has scored nine goals in 10 matches for Germany, enjoyed his return to north London.

Gnabry put on a devastating display of speed, skill and finishing to score with four of his five shots - netting twice in the space of 112 seconds, then twice more in the final 10 minutes.

His evening was so productive that he has scored as many goals at Tottenham Hotspur Stadium as Spurs striker Harry Kane has managed.

However, Gnabry is not even the most prolific player in Bayern's team.

Robert Lewandowski, who scored twice, with Gnabry setting up the first, has scored in every Bayern game this season bar the season-opening German Super Cup. That's 14 goals in his past nine games.
