Holland told The Mercury last week: "It's a case of getting my head down now, doing well in training, for the reserves and when I'm called on. I'm staying upbeat and battling for my place."
"I spoke to Curbs and told him I wanted to stay and fight for my place and he was happy with that. He told me I was a part of his plans, and that it was a long season and I'd get my chance.
"I still feel I have a lot to offer at this level - there's more to come. I spoke to a paper in Ipswich and said that one day I'd like to go back there. But that wasn't a hint that I wanted to go out on loan. That's not the case."
