Manchester United are “finalising a proposal” for Porto goalkeeper Diogo Costa, according to Correio da Manha.

The Portuguese newspaper claims that Porto need to raise funds by June 30th and they are more than willing to offload Costa in order to balance the books.

United are on the lookout for a new keeper to provide competition for David De Gea, but their interest in Costa has often been played down due to the cost of getting a deal done.

The Portuguese international, who has been capped 12 times by his country, has a €75m (£64m) release clause in his contract and, up until now, Porto have insisted that clubs pay the full amount.

Whether Porto’s financial situation has prompted United to make their move for Costa, we shall have to wait and see.

Costa is not the only goalkeeper that United have been linked with

A number of keepers have been mentioned as potential targets for the Red Devils, in addition to Costa, over the past few months.

Brentford’s David Raya is known to be on the club’s radar, although the likes of Tottenham and Chelsea have also been credited with an interest in the Spaniard.

Inter Milan’s Andre Onana, Aston Villa’s Emi Martinez, Borussia Dortmund’s Gregor Kobel and Dinamo Zagreb’s Dominik Livakovic are just some of the other names that United have looked at.

A lot could depend on De Gea’s contract

It has been claimed that the club’s current number one has agreed a new deal with the Red Devils which would keep him at Old Trafford beyond the summer.

However, the club have still now signed off on the contract, despite the fact that De Gea could leave at the end of the month on a free transfer. Were that to happen, recruiting a new keeper would take on greater importance, increasing the likelihood of a sizeable bid for someone like Costa.
