Manchester United boss Louis van Gaal remains keen on Porto defender Bruno Martins Indi.
The Holland international is quietly emerging as a top defensive transfer target for Van Gaal ahead of the summer market.
Record says United scouts were in the stands at Moreirense to see Julen Lopetegui's Porto win 2-0. It's understood Martins Indi was the prime target for United reps.
Van Gaal took Martins Indi to the World Cup with Holland ahead of the defender leaving Feyenoord to sign with Porto.
Also in attendance were scouts from Valencia and Juventus.
