West Ham manager Manuel Pellegrini has made central midfield his priority in January.
With Jack Wilshere and Carlos Sanchez both out with long-term injuries, West Ham are short in central midfield.
Declan Rice occupies the holding role but Pellegrini wants more competition for Mark Noble and Pedro Obiang.
This has led Pellegrini to target fellow Chilean Gary Medel, according to Sky Sports News.
But some latest reports indicate that West Ham may struggle to land their man.
Gary Medel bid rejected
According to Turkish media source Milliyet, Besiktas have rejected a bid worth €7m (around £6.5m) for Medel.
Despite struggling financially, the Turkish heavyweights are keen to keep the 31-year-old, who plays in central midfield or as a central defender.
Pellegrini was keen on the ex-Cardiff City man, but he should drop this interest rather than pay more than £6.5m for a veteran midfielder.
Instead, he should consider a swoop for a Tottenham Hotspur outcast.
Victor Wanyama: an alternative target?
West Ham could instead look at Victor Wanyama, who is down the pecking order at rivals Tottenham.
According to The Daily Mail, West Ham have discussed a move for the Kenya international, who has struggled with knee injuries lately.
With Moussa Sissoko playing well and Harry Winks and Oliver Skipp emerging as long-term options, Spurs might see Wanyama as surplus to requirements in the long-term.
But the 27-year-old could be a solid option for West Ham if he can regain full fitness.
Formerly of Southampton, Wanyama has plenty of experience providing protection for the defence, as well as scoring the occasional long-range strike.
Pellegrini may be worried about his injury record but Wanyama might be a risk worth taking, especially with Besiktas demanding silly money for Medel.
