According to British media talksport, 33-year-old Callum Wilson left Newcastle after the contract ends and is still waiting for the call of the new club.
Leeds United is believed to have been the main contender for signing Wilson, but West Ham can continue to stay in the Premier League if he is interested.
Wilson's agent Will Salterhouse is close to David Sullivan and he has contacted West Ham boss about possible transfers.

Wilson scored 49 goals and assisted 11 times for Newcastle, contributing 88 goals and 25 assists in a total of 239 games in the Premier League.
