Morrison has been one of the standout performers in the 2013/14 campaign, with the 20-year-old starting to fulfil the promise he showed in Manchester United's academy system.
It has taken longer than many anticipated for the highly-rated midfielder to deliver on his potential, with a move away from Old Trafford followed by a testing start to his time at Upton Park.
Morrison spent the 2012/13 campaign on loan at Birmingham City in the Championship, but used that spell to rebuild his confidence and burst onto the Premier League scene this term.
He has already opened his top flight goal account for the season and earned his first two caps for the England U21 side - with two goals scored in a 5-0 mauling of Lithuania on Tuesday.
After that contest, Morrison told West Ham TV: "I'm very happy with the performance on my second game for the U21s.
"My performance was good and so was the team performance, so we couldn't have hoped for much better.
"No matter what game I'm going into I always get nervous. Sometimes nerves can be a good thing, and they certainly were tonight.
"I've found it great being part of the squad, I've come in and the lads have treated me well and I've got on with everyone really well, so it's been good."
Next up for Morrison is a meeting with Manchester City - a contest he is looking forward to as an ex-United man and one he feels West Ham can spring a surprise in after returning to winning ways last time out against another title hopeful in the form of Tottenham Hotspur.
He added: "I'm very excited because obviously I used to play for Manchester United but I never played against their first team, so I'm really looking forward to it.
"Of course we can cause a shock. We're a great team and we should have had a lot of goals this season, but for some reason we haven't.
"Against Tottenham we managed to get the goals which have been missing, which was pleasing. The defence has been solid so if we carry on doing what we're doing, we can cause an upset."
