#6 Serge Gnabry

Arsene Wenger’s much-known eye for talent under the scanner with the transfer of teenage German international Serge Gnabry to Werder Bremen for around £5 million.
The availability of competing players in a similar position might be the one argument in Wenger’s favour but the fact that Bayern Munich snapped him up at the first chance after his impressive haul of 11 goals in 27 appearances with Bremen speaks volumes of his qualities.
While there are claims that there were efforts to retain him and Bayern influence behind the scenes, Arsenal might be left kicking themselves as he takes up more prominent roles in Bayern and German national career.
