ARSENAL manager Mikel Arteta has called on the club to upgrade his squad if he is to make it third time lucky and end a 21-year wait to win the Premier League this season.

The Spanish coach was speaking on the first day of the club’s pre-season tour of America in which they will play Bournemouth, Manchester United and Liverpool.
