ClaretandHugh revealed last week that the player would become a £10 million plus target at the end of the season and Sullivan has now made it clear we are keen to get the player.
Speaking to Sky Sports, he said: “Could he [Song] leave at the end of the season? Yes he could – loan players always can,”
“Barcelona paid £15m for him. You have to judge him over the season and I think Song has to judge West Ham over the season.
“He loves England and his family loves London. We hope that we can conclude a deal to sign him but if we can’t, we can’t.”
