Slaven Bilic has told Andy Carroll he has to show he can stay fit and injury-free this season if he wants to earn a new West Ham contract.

Carroll is approaching the time for talks over an extension to his deal, and the 28-year-old is set to start a third game on the trot when Tottenham visit the London Stadium for Saturday's derby.

'This is his season to be fit, to stay fit,' said West Ham manager Bilic. 'He's got two years (on his current contract). If we are talking about his contract, the question mark about him is his fitness, how much he is available during the season.'

While £16million summer signing Javier 'Chicharito' Hernandez has been used on the left wing by Bilic, the manager has warned Carroll he has stiff competition to stay as the No 1 striker.

'I don't think he was getting injured because he was sloppy and lazy and he thought, 'I have no competition, I will play anyway',' Bilic said.
