West Ham United manager Sam Allardyce has spoken of his delight at landing striker Andy Carroll on a six-year contract with an option for a further two years in the Club's favour.

24-year-old striker Carroll enjoyed a productive season whilst on loan with the Hammers last term and completed his move from Liverpool on a permanent basis earlier this week.

Allardyce described signing Carroll as his number one priority at the start of the close season, so was naturally pleased to complete the deal.

"After a long chase I am delighted that we have finally secured our very important acquisition in terms of ability and age," Big Sam exclusively told whufc.com 

"We expect him to enhance his reputation even further with West Ham and become one of the major strikers in the country and become an England regular - we hope he will produce for West Ham and England as we prepare to move into the Olympic Stadium in 2016.

"We've acquired a player who was recently the most expensive British player in the history of football. We haven't done it cheaply, but we have definitely done it wisely."

Allardyce believes the long-term nature of the contract penned by Carroll shows the belief the striker has in the Hammers' potential to keep on growing.

He continued: "The size of the contract is a statement of West Ham's belief in Andy and Andy's belief in West Ham. Our relationship over the 12 months he was here was key to this deal. He came to us in a difficult frame of mind and had suffered with injuries but the support the coaching staff and the rest of the boys that work so hard behind the scenes was something he felt very comfortable with in the end.

"He met new team-mates over the year and enjoyed their company and I think that definitely helped him to make the decision to return to West Ham. So not only did the loan pay off by us finishing tenth in our first season back in the Premier League but it has paid off by him choosing us.

"When I spoke to him I said look back at what happened at the back end of last season and the potential for what he can be. We are going to rely on him heavily to produce on a regular basis so he has pressure from that point of view. He will command a regular place if he's on top of his form. You can't guarantee a position to anyone but we think he can deliver the sort of performances and goals he should do.

"I told him we will improve him at West Ham while we're at the helm and will give him a chance to become a better player. It will reap rewards for us all. He can now put his experience of Liverpool behind him and show them what they missed by letting him go."

Allardyce also stated that Carroll's performances last season proved there is more to his game than just his aerial ability.

He added: "I said last season we didn't just use his aerial presence and pump it up to his head - we made the most of his playing ability, his ball skills, his ability to score goals in the air and on the ground, his hold up play and capability to dribble the ball past defenders. We've now got a combination of Andy Carroll with Matt Jarvis on one side and then either Joe Cole or Ricardo Vaz Te on the other.

"Kevin Nolan will once again complement Andy as he got ten last season and Andy got seven. So with Andy's signature secured, it means as an attacking force we will deliver thrilling times, particularly at the Boleyn Ground, like we did last season. We are still hoping to bring in some more new faces before the start of the season.

"I think Roy Hodgson will come and watch Andy and he will create the headlines for West Ham. It's very difficult to ignore Andy scoring goals and creating goals when England are so short. You can't look at the England side and see them going to the World Cup without Andy Carroll. If he's playing and scoring goals he could be first choice come the start of the World Cup if he wants to be."
