Barcelona are chasing Borussia Dortmund wing-back Raphael Guerreiro.

Marca says Barcelona are determined to sign a back-up to Jordi Alba this summer and Guerreiro is under consideration.

The Portuguese would not only compete with Alba but, with his contract coming to an end in 2020, he should be available at a reasonable cost.

Not only can Guerreiro play at left-back but he can also feature in midfield, as he often has done at Dortmund.

Filipe Luis seemed like the most likely option to arrive as his contract with Atletico Madrid is set to expire on June 30, but Guerreiro, 25, has now forced his way into Barcelona's thinking.
