West Ham United could turn their attentions to Rennes defender Jean-Armel Kana-Biyik, as Sam Allardyce prioritises the signing of a centre back, according to L’Equipe.

West Ham face competition to land the six foot Cameroonian from Celtic and Real Betis.

Kana-Biyik, 25, has made over 100 appearances for Rennes since signing in 2010 and is a full Cameroonian International.

Jean-Armel is the son of André Kana-Biyik who was sent off for Cameroon in the opening game of the 1990 World Cup against Argentina.
