Millwall are stepping up their efforts to sign the goalkeeper as the Lions look to improve their squad in this window.

Millwall are in advanced discussions to sign Sunderland goalkeeper Anthony Patterson as the January transfer window enters a decisive phase.
According to reports by Alan Nixon, the Lions are hopeful of reaching an agreement this week as they look to strengthen a key position ahead of the second half of the Championship season.
Talks between the two clubs are understood to be progressing, with Millwall pushing hard for a loan deal that would bring Patterson to The Den until the end of the campaign.
Sunderland, however, are keen to ensure any move reflects the goalkeeper’s long term value and have made it clear that they are not willing to sanction an exit without protective measures in place.
Sunderland view Anthony Patterson as a major asset despite his reduced role this season. The 25-year-old played a crucial part in the club’s promotion to the Premier League and remains highly rated by the coaching staff at the Stadium of Light.
As a result, the Black Cats are believed to be seeking a deal that covers as much of Patterson’s reported £25,000-a-week wages as possible.
There is also an appetite from Sunderland to include a commitment to buy if Patterson helps Millwall achieve promotion.
The club are understood to value him at around £8 million, a figure that reflects both his Championship pedigree and his age profile.
With a contract running until 2028, Sunderland are under no immediate pressure to sell and can afford to play hardball during negotiations.
Millwall’s preference is for a straight loan agreement. The club are wary of committing to a large transfer fee in the current market and are believed to value Patterson closer to £3 million.
While they may be open to inserting an option to buy if required, a mandatory purchase clause remains a sticking point.
The interest itself is not new. Earlier in the window, it was reported that Millwall were exploring a move for the Sunderland stopper as they assessed potential reinforcements between the posts.
That interest has since intensified, with the Lions now pushing to conclude a deal before the window closes.
From Millwall’s perspective, adding Patterson would represent a calculated gamble.
A goalkeeper with his experience could offer immediate stability, while a successful loan spell would justify a future permanent move if financial conditions align.
Born in North Shields in May 2000, Patterson is a product of Sunderland’s academy and has spent the majority of his career at the club.
After breaking into the first team during the 2021-22 season, he quickly became first choice and was instrumental during Sunderland’s promotion-winning campaign.
His performances at Championship level earned widespread praise, particularly for his reflex saves, composure under pressure and command of the penalty area.
Anthony Patterson has also represented England at Under-21 level, underlining his standing as one of the more promising English goalkeepers of his generation.
Despite that, increased competition for places and tactical changes have limited his game time this season, making a temporary move an attractive option for all parties involved.
Millwall have faced inconsistency in defensive areas this season, with their league position reflecting a side capable of strong performances but lacking control at key moments.
Team statistics show that the Lions have faced sustained pressure in matches, often relying on last-ditch defending and goalkeeping interventions.
A goalkeeper with Patterson’s track record at Championship level could offer leadership and reliability during the run-in.
His familiarity with promotion battles and high-stakes fixtures is another factor that appeals to Millwall’s recruitment team as they look to climb the table.
For the player, a move to The Den would likely provide regular first-team football, something that is essential at this stage of his career.
A strong loan spell could not only benefit Millwall but also place Patterson in a stronger position ahead of future decisions at Sunderland.
With negotiations ongoing, the next few days are expected to be crucial.
Millwall are keen to move quickly, while Sunderland continue to weigh up whether a loan with future conditions best serves their long term interests.
Other Championship clubs are believed to be monitoring the situation, meaning Millwall may need to act decisively if they want to secure Patterson’s signature.
Whether the deal ultimately materialises as a straight loan or includes additional clauses, it is shaping up to be one of the more intriguing moves of the window.
