Barcelona are ready to make a swap offer for Valencia fullback Joao Cancelo.
Barca have confirmed plans to make a fullback signing in the January market.
Sport says their search has led to Valencia and young Portuguese defender Cancelo.
And Barca aim to tempt Valencia by including Aleix Vidal in their bid for the wing-back.
The deal would suit Vidal, who is fed up this season after being frozen out by Barca coach Luis Enrique.
