The winter transfer window is now in full swing! As usual, Transfer Talk has its finger on the pulse when it comes to which rumours are picking up steam. Check out all the latest deals here.

Chelsea set to rival United for Semedo?

Toward the end of last year, Manchester United were strongly linked with a January move for Benfica defender Nelson Semedo.

The attack-minded right-back was reported to have been scouted by United when his club took on Napoli in the Champions League last month.

But Portuguese outlet A Bola reports that the 23-year-old, rated at almost £35 million, is now interesting Chelsea as well.

Meanwhile, after he was linked with both United and Paris Saint-Germain, news that Benfica's Goncalo Guedes was dropped to the bench at the weekend can mean only one thing, according to the Sun.

It says a £26 million move for the attacker is imminent and suggests Old Trafford is the likelier of the two potential destinations.

In October, it was reported that Guedes, 20, was being scouted as United weighed whether to make a move for a player described by some observers as "the next Ronaldo."

Portuguese newspaper Record believes the decision to leave him on the bench offered proof that he could soon be on the move.

PAPER TALK: Hull look to make transfer Mark

Lazar Markovic is out of the picture at parent club Liverpool and out of favour at loan home Sporting Lisbon, but he could soon be in favour at Hull City, sources have told ESPN FC.

Markovic has had a tough time in Lisbon, but that hasn't dented Hull's enthusiasm and the Tigers want to bring in the 22-year-old for the rest of the season.

Liverpool manager Jurgen Klopp, the Liverpool Echo says, would be fine with that, and talks are under way.

Because the loan agreement that took Markovic to Lisbon does not have a break clause, the agreement of the player, Liverpool and Sporting would be needed for it to be cut short.

The Serbia international winger cost Liverpool £20 million from Benfica in 2014 but appears to have no future at Anfield.

Deulofeu poised to wrap up Milan move

Last week, there was a bit of confusion over whether Everton winger Gerard Deulofeu had joined AC Milan on loan for the rest of the season. Yes, tweeted Milan. Not yet, said Everton.

Multiple reports said Goodison Park officials were angered by Milan's premature announcement, with the Serie A club later deleting their tweet and CEO Adriano Galliani stressing that negotiations were still ongoing.

Everton manager Ronald Koeman has made it clear that he will not stand in Deulofeu's way, and now Italy's Calciomercato suggests the player will undergo a medical in Milan on Monday, with an official announcement following later in the day.

It quotes him as saying Milan are "a great club" and adding that he would "have more to say tomorrow."

Tap-ins

-- On Saturday, sources told ESPN FC that Borussia Dortmund could beat Real Madrid in the battle for AIK teenager Alexander Isak, and the Guardian reports that talks on an £8.6 million deal to bring him to Germany are up and running.

Isak, 17, had appeared set for a move to the Bernabeu earlier this month, but the Guardian says the forward and his advisers "were in Dortmund on Sunday, working on concluding the deal."

It adds that they "are likely to have looked at the struggles of another Scandinavian prospect, Martin Odegaard, who has found it difficult since joining Real as a 16-year-old" and is now on loan at Dutch club Heerenveen.

-- Crystal Palace have been chasing Sunderland defender Patrick van Aanholt for what seems like most of the window so far -- and they will get him in the end, the Sun reports.

It says the Eagles "could bid as much as £12 million to force the deal through," leaving Black Cats boss David Moyes needing to seek defensive reinforcements of his own.

Sam Allardyce, though, doesn't sound as confident as the paper, admitting on Sunday that Palace have missed out on all their first-choice transfer targets.
