West Ham United manager Sam Allardyce delivered an insight into the reasons behind Ravel Morrison's exit after angrily rebuffing questions regarding the England Under-21 international on the day his contract at Upton Park was terminated.

Morrison signed a pre-contract agreement with Serie A club Lazio but will not play for the Hammers again this season after having the remaining six months on his deal cancelled by the Premier League club.

The 22-year-old is ineligible to play for a third different club this season having already represented West Ham and Cardiff City this term, and is likely to have to wait until next season to resume a football career which has lurched from one controversy to another.

After joining from Manchester United in January 2012, Morrison was subsequently loaned out to Birmingham City where he scored three times in 27 league appearances, showings which saw Allardyce include him in West Ham's first team squad for the start of the 2013/14 season.

Three goals in 16 Premier League games, including a breath-taking solo effort against Tottenham Hotspur, represented an impressive start to the campaign but he soon fell out of favour, moving to Queens Park Rangers at the back end of the season.

Just a single appearance for Morrison at West Ham this term came in August in the League Cup penalty shoot-out defeat to Sheffield United before he was shipped out on a third loan spell in as many seasons to Cardiff.

Allardyce has consistently criticised the attitude of Morrison, who in January was cleared of assaulting his ex-girlfriend and her mother, and his lack of compassion towards the player upon the confirmation of his departure gave an indication as to the relations between the pair.

Asked by a reporter whether he would like to comment on the end of Morrison's West Ham career following the 1-1 draw with Manchester United, Allardyce responded: "No."

Speaking in January, Allardyce said he was running out of patience with Morrison.

"Always. It's very difficult to sit and watch," he said. "There's only a certain amount of times you can advise and tell somebody what's the best way forward for them.

"He just has to change his whole life and then hopefully somewhere down the line he'll become the player he should be.

"Rav didn't perform at Cardiff. He went there to play games of football and try and reinvent himself. If he'd have done the business there he could have created a much more healthy position. He has left himself in a very difficult position."
