Las Palmas fear a deal for West Ham striker Jonathan Calleri is off.

Las Palmas have a medical booked for Calleri on Monday morning, with terms having been struck between all parties over a six month loan.

However, after featuring and scoring in victory at Middlesbrough, there's concern from Las Palmas that the deal is off.

West Ham may not now release Calleri unless they can find a replacement.

Meanwhile, in Gran Canaria, there remains hope the Argentine will arrive before the market shuts.
