Willock marked his first start with a goal against Ajax Amateurs in the KNVB Cup last month and is just focused on breaking into the starting line-up.
"I've really enjoyed it. It's a lot different playing football over here," he told the Manchester Evening News.
"We have a man at United that looks after the loan players and he's spoken to me a few times and keeps an eye on me.
"Obviously, it's in the back of my mind [breaking into the first team]. It's a dream but at the moment I'm just focusing on FC Utrecht."
