Arsenal legend Nigel Winterburn argues that Nuno Tavares doesn't know how to play the full-back role and believes the Portuguese defender needs to 'learn that side of the game very quickly'.
The former Benfica defender has been hooked early in his last two starts for the Gunners against Nottingham Forest and Crystal Palace, with Mikel Arteta deciding to select Granit Xhaka ahead of Tavares in last week's defeat to Brighton.
This has led to the 22-year-old receiving a fair amount of criticism and Winterburn believes that the main issue arises from Tavares not understanding the requirements needed to succeed as a left-back yet.
