Southampton have paid a club record fee of £22 million to sign Rennes and Ghana winger Kamaldeen Sulemana.
The 20-year-old has signed a four-and-a-half-year contract that will keep him at the Premier League club until 2027.
Sulemana joined Rennes from Nordsjaelland in 2021 and has appeared in 20 games this season, scoring once and assisting twice.
It exceeds the £20m Saints paid to sign Danny Ings from Liverpool in 2019.
Sulemana made three appearances at the World Cup in Qatar and was recorded running at 35.7kph (22.2mph) during the tournament, the quickest speed of any player.
“This is another really positive addition for us this month. We have been keen to add a little more potency to the side and Kamaldeen does that for us,” manager Nathan Jones said.
