The Arsenal shirt number of new signing Nuno Tavares has been confirmed.

The 21-year-old becomes the Gunners' first signing of the summer in a deal reportedly worth around £8million.

Tavares is a Portugal Under-21 international who has made 25 first-team appearances for the Lisbon club.

Tavares will wear the number 20 shirt for Arsenal, which was recently vacated by Shkodran Mustafi after he completed a move to Schalke in February.

Mustafi wore the number for the entirety of his time at the Emirates, but he largely failed to live up to his bumper transfer fee, developing a reputation as error-prone.
