Man Utd close on Mainoo and Maguire renewals – CAA Stellar and Triple S shape key contract talks at Old Trafford

David Ornstein: United advance on Mainoo and Maguire deals

According to David Ornstein, Manchester United are close to agreements with Kobbie Mainoo and Harry Maguire over new contracts, although work is still needed before everything is fully signed off. The proposed terms would keep Mainoo at Old Trafford until 2031 on improved terms, while Maguire has been offered a one-year deal with an option for a further year.

That would give United two different kinds of contract win at the same time: long-term security around one of the club’s most valuable young midfielders, and short-term continuity with an experienced centre-back who remains an important squad figure.

Mainoo’s side: CAA Stellar and a long-term play

Mainoo is represented by CAA Stellar, one of the biggest agencies in global football. The firm is widely known for operating at the top end of contract renewals and elite-market negotiations.

For Mainoo, a deal to 2031 would not just be about salary. It would also be about Manchester United protecting one of their core long-term assets and giving themselves maximum leverage in the years ahead.

Maguire’s side: Triple S Sports and another United link

Maguire is represented by Triple S Sports Management, the long-established UK agency that continues to handle high-profile Premier League work.

There is also a fresh Manchester United connection around the agency: as we recently covered, Kai Rooney has signed with Triple S Sports as well, extending the agency’s links inside the wider United ecosystem.

Why these two renewals matter differently

The Mainoo and Maguire talks matter for different reasons. Mainoo is a future-value contract: younger, longer, more expensive, and central to the club’s next era. Maguire’s deal is more about experienced depth and continuity, especially in a position where leadership, reliability and dressing-room balance still matter a lot.

In both cases, United are trying to avoid uncertainty. A 2031 deal for Mainoo would remove a major long-term contract storyline, while a 1+1 for Maguire would give the club flexibility without losing a senior option too soon.

The key point in Ornstein’s reporting is that the talks are advanced, but not yet fully complete. So the next step is straightforward: final agreement on the remaining details, then signatures. If both deals are finalised, United will have secured a significant double contract boost before the summer market fully heats up.
