David Sullivan has hailed West Ham striker Andy Carroll.

West Ham United co-chairman David Sullivan has told the club's official site that striker Andy Carroll has made a 'huge impact' since his return from injury.

Carroll, 26, has been blighted by a number of injuries since joining West Ham permanently from Liverpool in 2013, and he started this season on the sidelines.

Now though, the former Newcastle star is back in action, and he is certainly the man of the moment at Upton Park after his heroics on Saturday.

West Ham beat Premier League champions Chelsea 2-1, and whilst Mauro Zarate bagged the opener - only for Gary Cahill to equalise for the Blues - it was Carroll who won the game for Slaven Bilic's men, rising highest with a trademark header from Aaron Cresswell's cross.

Carroll's size and sensational leaping ability make him one of the most dangerous aerial threats in the Premier League, and West Ham certainly exploited that against Chelsea.

Now, the burly target man will be hoping to win a place in the England squad for next summer's European Championships in France, and he has been given a ringing endorsement by David Sullivan.

The Hammers co-chairman has told the club's official website that Carroll has made a huge impact in recent weeks, and that the striker deserves his success having worked so hard to recover from yet another injury.

"Andy Carroll is starting to come back and it was great to see him score the winner against Chelsea on Saturday," said Sullivan. "You could argue that he has made an impact in the last three games that he has come on since the Norwich game."

"He was involved in the injury time equaliser that Kouyate scored, he set up the second goal for Manuel Lanzini against Crystal Palace and got the winner on Saturday. He has had a huge impact. There is no reason why that cannot continue. We all want him to do well. He has trained incredibly hard and on his day he can make a contribution," he added.

The key to Carroll's season will be whether he can stay fit, as niggling injuries have haunted him throughout his career - but if he can stay away from the treatment table, West Ham have a major weapon at their disposal, with few defences able to cope with Carroll's aerial prowess.
