Manchester United must compete with Real Madrid if they want to sign Villarreal defender Pau Torres.
AS says United are willing to launch a transfer bid for Torres.
But they face competition from Real Madrid for the defender's signature.
Ole Gunnar Solskjaer wants to bring in a new centre-back this summer as a long-term partner for Harry Maguire.
And according to AS, the Red Devils may make an official bid in the coming weeks.
Torres, 24, enjoyed a fine season with boyhood club Villarreal and capped it off by lifting the Europa League, beating United in a marathon penalty shootout.
He has been with the club since 2002, aged just five, and has racked up 88 first-team appearances, earning himself a starting spot for Spain at Euro 2020.
