The Hammers took the Cameroonian on loan from Barcelona over the summer on the back of a poor two-year spell following a big money move from Arsenal.
A number of other clubs were linked with him at the time, but the Irons’ gamble has, thus far, paid off, with Song having been one of the club’s key performers in a season that has exceeded expectations.
As a result of his fine form, some of the Premier League’s ‘big boys’ – in particular Liverpool – have been linked with end of season offers for Song, and with Champions League football unlikely in east London, their chances of keeping him appear slim.
After an underwhelming winter transfer window, West Ham are understood to be acting quickly ahead of the summer, with Iborra on their radar.
Reports suggest the 27-year-old holding midfielder has been identified as a target, with his robust showings for Sevilla having earned him much praise.
