Having spent time with the Irons, as well as Cardiff City this season, the England Under-21 international cannot play for Lazio this term, as he would break UEFA rulings.
However, having been cast out of the West Ham squad by Sam Allardyce, there is clearly no future at the Boleyn Ground for him, and it has been reported by La Gazzetta dello Sport that he has completed his first training session with his new club.
Well regarded for his exceptional talents, the youngster’s career - which started at Manchester United - has somewhat stalled in the last few seasons. He has had well reported off-field issues which have limited his development, and, since signing for the Hammers in 2012, he has managed just 18 appearances.
A loan with Birmingham City was impressive, although a follow up loan with Cardiff did little to improve his reputation as he was allowed to leave Wales early after just seven games.
It is good to see that Morrison has chosen to move abroad, as it is often a limit on English players that they are too afraid to move to foreign football.
If the youngster can finally sort his career out, it would come as no surprise to see him finally fulfil his potential that has earmarked him as a future England international star.
