Cambridge United’s transfer plans suffered a setback on Sunday after Millwall midfielder Adam Mayor entered advanced talks with Scottish Premiership side Hibernian. The 21-year-old, who impressed during his loan spell at the Abbey Stadium last season, is edging closer to a permanent move north of the border - and the U’s must now look elsewhere.

What happened to Adam Mayor?

Adam Mayor spent the 2025/26 campaign on loan at Cambridge United, where he became a key figure under Neil Harris. The Millwall loanee scored three goals in 34 appearances as the U’s secured promotion to League One. His displays caught the eye, but Millwall head coach Alex Neil confirmed the club had rejected a permanent approach from Cambridge. The Lions boss even hinted at a possible return to first-team action for Mayor this pre-season in Spain.

Yet just days later, reports emerged that Mayor is in advanced talks with Hibernian. The Scottish side are closing in on a permanent deal, leaving Cambridge United to reassess their options. The midfielder has only made six appearances for Millwall since joining from Morecambe in January 2024, with a hamstring injury sidelining him for the first half of last season.

Why it matters for Cambridge United

Mayor’s potential departure is a blow for Cambridge United, who finished third in League Two last term with 82 points from 46 games. The U’s had been keen to bring him back permanently, with director of football Mark Bonner admitting he’d “love” to add the midfielder. Bonner said: “He’s one we’d love to try to add, but at the same time there will be a lot of people interested in him.”

The loss of Mayor comes as Cambridge United sit five points behind Bromley in the League Two title race. Their recent form - two wins, two draws and a loss in their last five - shows they’re still competitive, but the squad now needs shoring up. The U’s last result was a 0-0 draw at Crewe on 2 May 2026, a game played in front of a sparse crowd.

What comes next for the U’s?

With Mayor’s future uncertain, Cambridge United must act fast. The club has already lost Barry Bannan and Macaulay Langstaff this summer, and their League One campaign kicks off in just over a month. Mark Bonner’s scouting network will be working overtime to find a replacement who can replicate Mayor’s creativity and goalscoring threat.

The U’s have shipped 33 goals this season but boast a +33 goal difference, showing their defensive resilience. Their recent form (DDWWL) suggests they’re peaking at the right time, but the Mayor-shaped hole in midfield needs filling. The race for promotion is wide open, and Cambridge United can’t afford to stand still.

Cambridge United are third in League Two with 82 points from 46 games and five points behind Bromley.
