Southampton Football Club have announced the signing of centre-back Mohammed Salisu from Real Valladolid for a fee of £10.9m.

The sought-after 21-year-old Ghanaian has signed a four-year contract at St Mary’s, becoming the second player to arrive at the club during this year’s summer transfer window.

One of the most highly-regarded young centre backs playing in Europe right now, Salisu moved to Spanish top-flight side Valladolid from his homeland in 2017, first establishing himself in their second side, before quickly progressing into a key member of the first-team.

Salisu featured twice in the club’s Copa del Rey campaign in the 2018/19 season before becoming a regular in the 2019/20 campaign, making 32 appearances across all competitions, helping them to a notable improvement in their defensive record and also to a respectable 13th-placed finish.

Southampton manager Ralph Hasenhuttl said: “This is an important signing for us. Mohammed is a player who fits our profile well. He is young and has a great amount of potential, but he is also someone who has the qualities to come in and help the team as soon as he is up to speed with our way of playing.”

“I know that the team expects a lot from me and I’m going to try to give all I can to help the team.”
