Joe Allen could leave relegated Stoke City for £25 million this summer – if a top-six Premier League club comes in for him.

Allen’s contract includes a complex clause which allows Manchester City, Manchester United, Spurs, Arsenal and Chelsea to sign him for a set price, following Stoke’s relegation to the Championship.

The clause does not apply to former club Liverpool, who sold the Wales international to Stoke for £13m in July 2016, but the five other elite clubs can trigger his release by offering £25m.

Stoke are in a strong position to receive a substantial profit on the 28 year-old, as it is understood they can name their price to any other club.

West Ham had a proposal of around £25m rejected for Allen in January, and remain interested, but Stoke are ready to adopt a hardline stance on the midfielder’s future.
