West Ham manager Slaven Bilic has admitted that Andy Carroll’s latest knee injury raises a “big question mark” and that he no longer feels like he can count on the former England striker.

Carroll, who has played only 81 league games during more than four years at West Ham, has been ruled out for between four and six weeks. He wrote on Twitter that he was “devastated” about his latest injury - and claimed still to be the “15-20 goal man” – even if Bilic appears to be running out of patience.
