Jonny Evans
Leicester City are trying to sign Jonny Evans from West Brom and the Hammers should join that race if we want a centre back.
The Northern Ireland international is likely to be available for a similar price to Kone, if not cheaper, and he is a much better player than the Sunderland defender.
With experience of playing at Manchester United, Evans is a seasoned Premier League performer who regularly turns in reliable displays for West Brom.
The 29-year-old still has several years left in him so he could be a shrewd addition if we move quickly.
