Last season was a contrasting campaign for Nuno Tavares, with the left-back having to fill in regularly for the injured Kieran Tierney and making 28 appearances in all competitions for Arsenal.
His attacking qualities were widely praised while at the Emirates, but his defensive frailties led to him being substituted twice at half-time during matches, most notably during January's FA Cup defeat at the hands of then Championship side Nottingham Forest.
However, the player was supported by Arteta, who has sent the 22-year-old out on loan to Marseille this season rather than seeking a permanent deal once it is finished.
