Porto goalkeeper Diogo Costa is emerging as a serious target for Manchester United.
The Red Devils are in the market for a new number one goalkeeper when the transfer window opens.
Even if David De Gea renews his contract, media reports have stated that United want a new no.1 who is more suitable to manager Erik Ten Hag's tactics.
Per Record in Portugal, Costa may end up being that goalkeeper for United.
However, they will have to face competition for his signature from a host of other teams.
The likes of Tottenham and Bayern Munich are also very keen on Costa.
