Enzo Fernandez could become the Premier League’s most expensive player should Chelsea sign the World Cup-winning midfielder from Benfica for a reported 120 million euro (£105.5m) fee.
That would eclipse the £100m sum paid by Manchester City for Jack Grealish when he joined from Aston Villa in August 2021.
The PA news agency understands Tottenham Hotspur remain cautiously optimistic about completing a transfer for Sporting right-back Pedro Porro before Tuesday’s deadline.
The deal looked to have collapsed earlier this week, but now appears back on for a fee understood to be around £39.5m.
Meanwhile the future of Moises Caicedo remains uncertain, with the midfielder seeking a move to Arsenal and Brighton determined not to sell.
Brighton turned down Arsenal’s initial offer of £60m for the Ecuador international, but Caicedo then publicly declared he wanted to leave to “take up this magnificent opportunity”.
Brighton are digging their heels in, however, and although Caicedo was left out of the squad which beat Liverpool in the FA Cup on Sunday, boss Roberto De Zerbi reiterated that he wants to keep the 21-year-old for the rest of the season.
He said: “Caicedo is a very good guy. I understand it when you are 21 and the chance of a big team in Europe. But I would like him to finish the season with us.”
But Arsenal are expected to come back with an improved offer while Chelsea have also been linked.
Joao Felix, Benoit Badiashile, David Datro Fofana, Mykhailo Mudryk, Andrey Santos and Noni Madueke have already arrived at Stamford Bridge this month.
Brighton, meanwhile, have brought in a midfielder, Yasin Ayari from Swedish side AIK, but the 19-year-old is seen as one for the future and not a replacement for Caicedo.
Elsewhere, Manchester City are not expected to be busy on deadline day despite the shock proposed loan move of Joao Cancelo to Bayern Munich.
Similarly, Manchester United appear to have completed their business apart from the possibility of one or two fringe players going out on loan.
Reports claim Tottenham’s move for Sporting Lisbon’s Pedro Porro is in the balance with negotiations likely to go down to the wire.
The north London club announced on Monday evening that midfielder Bryan Gil has joined Sevilla on loan until the end of the season.
Brentford would like to take Spurs outcast Djed Spence on loan.
Newcastle have brought in Anthony Gordon from Everton but they are not finished yet, with Eddie Howe seeking a loan replacement for Nottingham Forest-bound Jonjo Shelvey.
The Magpies are also close to completing the signing of young full-back Harrison Ashby from West Ham.
The Hammers need a centre-half after selling Craig Dawson to Wolves and were linked with Everton’s Michael Keane, but the arrival of new manager Sean Dyche at Goodison Park has muddied the waters there.
West Ham striker Michail Antonio seems to be angling for a move but injuries to all of the club’s other forwards mean he is unlikely to get his wish.
Fellow strugglers Southampton need a new attacking option and are reportedly keen on Rennes winger Kamaldeen Sulemana.
Saints boss Nathan Jones on Monday poured cold water on rumours linking striker Che Adams with Everton.
