Mohammed Salisu passed a Southampton medical in Spain yesterday, Football Insider can reveal.

The Ghanian defender, 21, has agreed to join the Saints from Real Valladolid and finalised the transfer by undergoing his physical examination on the Continent.

A Southampton source has told Football Insider that the formalities of the transfer are now all complete.

The Premier League club have agreed to pay the £10.9m (€12m) release clause in the Salisu’s Valladolid contract as well as hand him a four-year deal worth £35,000-a-year.

He cannot be formally registered until a work permit is obtained but the Saints believe that to be a formality.

Ralph Hasenhuttl and the Southampton recruitment team have moved quickly to strengthen the team’s defence ahead of the Premier League window opening next week.

Hasenhuttl has won plaudits for his side’s adventurous attacking play but they have shipped 59 goals in their 37 league matches.

Salisu is a left-footed centre-back who stands at 6ft 3ins and has been a mainstay of the Valladolid team this season.

He started 30 of their 38 La Liga matches this season after graduating from their B team.

Salisu has made it clear to the Spanish side he wants to play in the Premier League with Southampton, who have worked quickly to meet his release clause.
