Morrison was blocked from speaking with the media last season, but spoke yesterday about his time St Andrews.
"I missed West Ham a lot but it was still good in the Championship," the former Manchester United youngster said.
"I probably enjoyed the game against Millwall the most, when we came back from 3-0 down to draw 3-3. That was probably the best game because the whole team worked hard. I also scored a couple of good goals."
Morrison is looking ahead after starting pre-season with West Ham as they prepare for the new Premier League season.
He said: "Hopefully I can get an opportunity. I've just got to carry on working hard in pre-season and show the manager what I can do."
