Manchester United Transfer Rumours: Sneijder, Muniain, Javi Martinez, Alba, Fabio Involved In Latest News

While a deal for Benfica's Nicloas Gaitan appears all but done, there is plenty of other speculation surrounding Manchester United's transfer activity for the upcoming summer.

And the man who dominated the rumor mill last summer, Wesley Sneijder, could once again be on the agenda for United, according to Sport Witness.

The website refers to a story in Italian publication Calciomercato, which claims that Zenit St Petersburg are lining up a move for the Dutch international at the end of the season, with Inter open to moving him on.

Manchester United were heavily linked with the attacking midfielder through much of the last close season, but a deal could not be reached, reportedly due to the Premier League champions being unwilling to match Sneijder's current high wages.

But, with the 27-year-old having a difficult season in a struggling Inter side, the Italian club could substantially lower their asking price, making the financial package more amenable to potential suitors.

Sneijder has been in and out with injury this campaign and managers Gian Piero Gasperini and Claudio Ranieri have also struggled to accommodate him in their systems.

But, although the playmaker still has undoubted talent, United may be unwilling to lay down what would still be a hefty sum of money on a player who will be 28 in June, especially with injuries a concern.

And with United tying up a deal for Gaitan, it is unlikely the club will go in for the similarly-skilled Sneijder.

Another attacking-minded player linked to a move to Old Trafford on Monday is Iker Muniain. The 19-year-old Athletic Bilbao winger first emerged as a potential target for Sir Alex Ferguson after he played superbly as Bilbao tore United to shreds in both legs of the Europa League tie with United.

The Spanish international will be the subject of a £20 million ($32m) bid by United this summer, according to the Daily Express.

Clearly Bilbao's performance made an impression on Ferguson, as Munian's team mate Javi Martinez also continues to be linked to an Old Trafford move.

According to Caught Offside, Spanish international Martinez is the man sought by Ferguson to be the lynchpin of his midfield next season.

Continuing the Spanish theme, the website also claims that United are pursing Valencia left-back Jordi Alba.

It is a deal that is hard to envisage coming to fruition, however, given Patrice Evra's stranglehold over the left-back slot at Old Trafford. The Frenchman may not have had his best season, but it would still be a surprise should Ferguson usher in a replacement.

There could be room for a back-up full back at United next season, though, with the Daily Mirror reporting that Fabio will be allowed to leave on-loan next season. It has been claiomed elsewhere that the Brazilian will reportedly be part of the deal that sees Gaitan arrive from Benfica, but according to the Mirror, Fabio could be spending the season in Lisbon regardless.

There is the possibility that Fabio could go to Benfica, Fabio's agent Cassiano Pereira told O Jogo, according to the Mirror. Alex Ferguson has already talked to me and Fabio about that possibility, and in the next two or three weeks we will make a decision.
