The summer and January transfer windows delivered some stellar additions to the Premier League this season. From midfield architects to dynamic attackers, several new arrivals have made an immediate and meaningful impact on their clubs and the wider title picture.

Whether you were browsing correct score and goalscorer odds during the run-in or simply following the table, these are the players who have justified their fees and then some.

Here is our pick of the standout signings of the 2025-26 campaign, with online football betting markets already reflecting how pivotal each of them has become.

1. Martin Zubimendi, Arsenal

There were question marks when Arsenal finally secured the Spaniard's signature from Real Sociedad, given he had previously rejected Liverpool's approach and seemed destined to stay in La Liga.

Those doubts have been well and truly buried. Zubimendi has slotted seamlessly alongside Declan Rice in the centre of the park, forming a partnership that has given Arsenal a steel and sophistication they have sometimes lacked in the big moments.

Five Premier League goals in 30 appearances is a remarkable return for a defensive midfielder, including a brace in the 3-0 win over Nottingham Forest that won him the Goal of the Month award for September.

As Arsenal lifted the title this season, Zubimendi's arrival will be cited as the moment they went from nearly men to genuine champions.

2. Joao Pedro, Chelsea

The Brazilian has been one of the most consistent performers in the league this season, contributing 14 goals and five assists in 32 Premier League appearances. Chelsea's recruitment record has been the subject of significant scrutiny in recent years, but Joao Pedro looks like a signing that will stand up to any level of examination.

His movement in and around the box is intelligent, he links play effectively, and his goal return has kept Chelsea competitive throughout the season. At 23, he looks like the kind of striker the club can build around for years to come.

3. Antoine Semenyo, Manchester City

The January window is not always associated with transformative business, but City's decision to bring Semenyo to the Etihad has had a genuine impact on their season. Five goals and an assist in just 10 Premier League appearances since his arrival is a remarkable return, and his directness and pace have given Guardiola's side an extra dimension in wide areas.

City were stuttering before his arrival, and Semenyo has been a key part of their resurgence in the title race. A bargain by any measure.

4. Rayan Cherki, Manchester City

The 22-year-old French winger arrived from Lyon in the summer carrying considerable expectation, and he has largely delivered. Three goals and 10 assists in 26 Premier League appearances reflect a player who has taken time to fully settle but has grown in influence as the season has progressed.

Cherki's ability to play across the front line, his both-footed skill and his capacity to unlock defences with a single pass have made him a consistent threat. Guardiola's comment that he sometimes wants to kiss him and other times wants to shout at him captures the fine margins of a young player still finding his ceiling, but the output speaks for itself.

5. Granit Xhaka, Sunderland

This one raised eyebrows in the summer. A 33-year-old defensive midfielder, Bundesliga title winner or not, returning to the Premier League with a newly promoted side felt like an odd fit. Nobody is raising eyebrows now.

Xhaka was named club captain by Régis Le Bris before a ball had been kicked, and he has led by example in every sense. One goal and five assists in 27 appearances barely tell the story: it is his defensive output, his reading of the game and his ability to organise those around him that have made Sunderland one of the stories of the season.

The Black Cats sit 10th and are just one point off the top seven, with European football a genuine possibility. Several of Sunderland's summer signings have impressed, with Robin Roefs and Nordi Mukiele both earning plaudits, but Xhaka has been the heartbeat of everything they have done. A remarkable return.
