Leicester City have signed defensive midfielder Wilfred Ndidi for a reported £15m from Belgian side Genk. The 20-year-old Nigeria international completed his move on Thursday after a work permit was approved, signing a five-and-a-half-year deal. Ndidi has already trained with the squad and could make his debut in Saturday’s FA Cup third-round tie at Everton. “He’s an impressive player with a big future,” said manager Claudio Ranieri. “I feel I can learn a lot here,” Ndidi told the club’s TV channel. “I try to win the balls for the team – that is one of my main attributes. I have to achieve a lot here.” Ndidi helped Genk finish top of their Europa League group to secure their place in the knockout stages of this season’s competition.
