Barcelona have reportedly identified Borussia Dortmund centre-back Raphael Guerreiro as a potential summer target, according to AS.

The Spanish champions have been strongly linked with Real Betis defender Junior Firpo, but see Guerreiro as a cheaper alternative.

The report claims the Catalan giants want to create competition for Jordi Alba, but see Firpo expensive at £25m.

Guerreiro, 25, is also thought to be worth around £25m but, with his current contract is set to expire in 2020.

The Portuguese racked up 32 appearances for BVB last season.
