Carroll had been on loan to West Ham all season, where Carrol scored seven goals in an injury riddled season. But when he was healthy, Carroll showed how good a player he is.
‘I have enjoyed every minute of being here,’ he told whufc.com.
‘I have just tried to play my best in every match, score goals and keep myself fit once I got back from the injuries I had and then push on from there.
‘I have worked hard to get myself back in the England squad, trying to play my best for West Ham, so I am really pleased about that.
I just have to make sure I keep playing well to stay in there.
‘I have had a great season here at West Ham, really enjoyed being part of a great set of lads in the team, with the staff around us and the fans.
‘Everyone has been so welcoming to me and I have been over the moon to be here. This is a great club.’
A £15m price tag is a massive loss for Liverpool who paid a Torres inflated price of £35m in January 2011 for the former Newcastle center forward.
When Brendan Rodgers took over as Liverpool manager a year ago, he made it crystal clear that a big target man like Carroll did not fit into his tika-taka style of football. Which is why he was sent to West Ham at the end of August.
It is a great signing for West Ham and Carroll. The £15m price tag that he carries now, will not have the same burden and expectations as when he moved to Liverpool. Plus, Big Sam plays the style of football that fits Carroll’s style. Carroll will be the focal point of the Hammers attack next season, and Allardyce will make sure that they provide Carroll with the kind of service that will play to his strengths.
