The 19-year-old joined West Ham from Premier League side Manchester United last month, but has yet to feature for his new club.
“I can feel myself getting sharper and stronger with each training session,” Morrison said.
“I’m not sure how long it’ll be until I’m ready for the first team but I’m looking forward to it when it happens.
“I was at the Southampton match the other night and it was a great game. Robert Green was superb and pulled off some world-class saves.
“The atmosphere was electric and I’m looking forward to playing in front of the crowd even more now.”
