Sam Allardyce makes brutally honest comments about West Ham ace Andy Carroll

Sam Allardyce believes Andy Carroll doesn't put enough work in.

Sunderland manager Sam Allardyce has told The Sun that Andy Carroll is too casual - and could be England's main striker if he worked harder.

Allardyce, 60, made his return to football on Friday by taking the reins at Sunderland, five months after losing his job as West Ham boss.

A 2-0 defeat to Newcastle United on the final day of last season proved to be Allardyce's final game as Hammers manager, capping off a torrid second half of the season.

Now though, Allardyce is back in Premier League management - and has been reflecting on his time in charge at Upton Park.

Speaking to The Sun, Allardyce has been speaking about West Ham striker Andy Carroll - and gave his brutally honest verdict on the giant forward, claiming that the 26-year-old can be better than he is, if he just worked a little harder.

"Andy Carroll could be an even better player if he pushed himself and put the work in," said Allardyce. "He tells you he does — but he doesn’t always do it.He doesn’t really like watching football and isn’t interested in the history of the game. Andy certainly wouldn’t be in your football quiz team."

"He treats life a bit too casually. He also gets himself into situations off the pitch which a manager can do without — and so can he. He needs to be more responsible and realise that a football career passes in the blink of an eye. Carroll loves being the main man when he’s on the pitch. He never goes hiding. When fit, he should be England’s regular centre-forward," he added.

Carroll initially joined West Ham on loan in 2012 following a famously dismal spell with Liverpool, and having impressed in Allardyce's direct style of play, he penned a permanent deal in 2013.

Since then, Carroll has played just 35 games for West Ham, suffering a spate of injury problems, which have certainly stalled Carroll's career.

It remains to be seen how important Carroll will be under new Hammers boss Slaven Bilic, but the striker should heed Allardyce's advice and really push to improve - especially having gained such a negative reputation in recent years, mostly for those injuries and his off-field activity.
