Mourinho's interest in Samuel Umtiti is well known, with United prepared to meet the Barca defender's €60m buyout clause.
However, Don Balon says the Frenchman isn't the only Barca player on Mourinho's radar.
Andre Gomes is also under consideration, with Barca actively encouraging offers for the Portugal international. Gomes shares the same agent, Jorge Mendes, as Mourinho.
His buyout clause is set at €180m, however United intermediaries have informed Mourinho that Barca would be willing to sell for €100m.
