West Ham United have upped their bid for Huddersfield Town striker Jordan Rhodes.

The Daily Mail says Sam Allardyce had offered £4million for Rhodes, 21, last week, but Huddersfield insist he is not for sale, particularly after his five-goal show against Wycombe attracted more interest from Premier League clubs such as Everton.

However, West Ham think the player wants to join them and will offer £4.5m with more cash up front, to further test Huddersfield's resolve.
