The mural was defaced after Barca sporting director Deco said they could target the winger, who scored in last year’s European Championship final against England to guide Spain to a record fourth title. Williams’ new release clause is likely to put off Arsenal for now, but the Gunners do remain keen to sign a new wide forward.

A cheaper option could arrive in the form of Marcus Rashford, who is angling for a clean break from Manchester United this summer. The feeling appears to be mutual, given that his shirt number has already been taken by new signing Matheus Cunha.

The Catalan club were rebuffed by Athletic Club last summer and had to compete with Bayern Munich for the winger.
