The Cottagers have unveiled Calvin Bassey as their latest summer addition after reaching an agreement with Ajax over a €21m (£18m) transfer, thepapers.ng reports.
The deal is subject to international clearance, which the club have said should be received during the early stages of next week.
Bassey has put pen to paper on a four-year deal until the summer of 2027, with an option for Fulham to extend by a further 12 months.
Speaking to FFCtv, Bassey said: “I know how big of a club Fulham is. They always have quality players, they’re playing in the Premier League, the best league in the world, so I didn’t have to think much about it.
“It’s a London club as well, so it’s always a plus to go home! I’m happy it’s all done now and I can just focus on the football and help the team build on last season, when they did amazing.”
Fulham vice-chairman Tony Khan added; “I’m thrilled to welcome Calvin Bassey to Fulham Football Club! He’s a young and versatile defender; a homegrown player who developed at Leicester City’s academy before moving on to play for Rangers and then for Ajax, as well as Nigeria’s national team.
“Calvin’s been a top target for us, so we’re all delighted that he’s committed for the long term with Fulham, and we’re looking forward to watching him progress.”
