Andy Carroll is undergoing a medical with West Ham United ahead of his proposed £15m move from Liverpool.

The Hammers agreed a fee with Liverpool In May after the striker impressed after a season long loan at Upton Park, but Carroll was unsure whether to commit to a permanent deal.

It would now appear that the England international has agreed to join the club on a permanent basis after undergoing a medical with West Ham on Tuesday, BBC Sport report.

Hammers manager Sam Allardyce has been keen to secure the 23-year-old's services on a long-term basis after it became clear that Liverpool's Brendan Rodgers did not envisage Carroll playing a part in his squad as he continues to shape a Liverpool squad in his own image.

"If we can start with Andy Carroll (next season), that would be a great achievement for us as he can only get better and better," Allardyce said following West Ham's final game of last season.

"Then we can build around that in terms of how we want to improve next year, with better quality.

"Andy is a player who is wanting to enjoy his football. He lives for his football and wants to play every game. He wants to use his strengths and score as many as he can - but he also works very hard for the team."

The Gateshead-born forward endured a number of injuries during his loan spell in East London, with knee and hamstring issues hampering a season where he struck seven goals in 24 appearances.

Due to his injury record, Carroll will likely have to complete a rigorous medical before the club confirm the deal, but Allardyce would seem intent on making the former Newcastle United man the focal point of his attack in time for the new season.

Brendan Rodgers has previously indicated that he was looking to resolve the Carroll issue as quickly as possible after telling the striker last season that his first team chances at Anfield would be limited.
