The German attacker has become an FCB star despite never really impressing in England
Former West Brom coach Tony Pulis admits he's shocked at Serge Gnabry's transformation after seeing him score four Champions League goals for Bayern Munich in a 7-2 win over Tottenham .
The former Arsenal attacker spent a few months on loan at the Baggies in 2015 with fitness concerns seeing him make just three appearances for the club before being recalled by the Gunners in January.
Unable to secure game time at the Emirates, Gnabry moved to Werder Bremem permanently in 2016 before being signed by Bayern one year later.
