One of Arsenal's greatest mistakes in the transfer market in recent years was arguably letting go of Serge Gnabry. The winger spent five years at the Emirates Stadium, but he made only 18 first-team appearances for the Gunners, and his time at the club ended with an unsuccessful loan spell at West Bromwich Albion.
Since then, Gnabry has won four Bundesliga titles with Bayern Munich, a Champions League and a Club World Cup. He has established himself as a world-class talent, directly contributing to 110 goals in 179 appearances for the German club. Few people would have predicted Gnabry's success, and Arsenal's decision to sell him to Werder Bremen for a fee in the region of £8 million in 2016 has not aged well.
However, Gunners legend Martin Keown believes Arsenal could have their new Gnabry. Marquinhos impressed on his Arsenal debut, scoring in the Gunners' 2-1 win at FC Zurich in the Europa League on Thursday night. The teenager signed from Sao Paulo this summer and Arsenal fans got a first glimpse of the Brazilian during the victory in Switzerland.
