The young striker re-joined the club last week following some time away from the game and is looking forward to a second spell at Oldham.
Dearnley who spent time on loan at Boundary Park just over twelve months ago comes with an impressive background after being at Manchester United throughout his whole youth career before his release. Now the 21 year-old wants to make a name for himself in the Football League.
"I'm delighted to be back here after my loan spell last year and for me it was the best few months I've had in football. I really enjoyed my time at the club.
"With my loan last year it was a good time scoring on my debut, so it's nice the fans will be aware of me and it was an easy decision to make."
He added: "I learnt a lot whilst here in my first spell as U23s football is completely different to first-team football. So now I'm coming in with a bit more experience, I know about what is expected going into games so you definitely learn a lot being on loan and would recommend it to any young player really."
Getting released at such a young age and with plenty still to offer the young forward took time out over the summer for personal reasons and to assess his options before making a return.
A sensible move that looks to have paid off as he rejoins Latics more focused and more determined to improve.
"I had a bit of time out of football, some things happened, I've reflected on it and learnt from it. So I'm getting fit now and happy to be back at Oldham.
"It was good to detach yourself away from football sometimes as it can be demanding and allowed me to just get back to basics, relax, chill-out and recover."
Before coming back to Oldham, Dearnley spent time figuring out if it would work for both parties and after a lengthy chat with the Head Coach it confirmed his decision that he could be of benefit to the team.
"I met the gaffer before signing and he seems really good and nice. He just said to come in, enjoy it, get fit, get back playing and move on from there.
"When I walked back into the place all of the lads were sound it felt like we knew each other for a long time.
"I like everyone and get on with everyone so there's not a problem and I can concentrate on my football now with the tight knit group."
After signing for the club, Dearnley was an unused substitute at Stevenage in the week before coming on in the closing stages at the weekend at home to Carlisle making an impactful appearance and gave a glimpse to everyone what is to come with more hard work.
"You've got to give your all for the club, it's like everything in life. I've scored one goal for the club last season and obviously I would've liked to score more, but for this time round I know I will get a few more goals and I think it's important to keep the fans onside because at the end of the day you're playing for them, it's their club as well.
"The fans that know me from last year, my debut from the people that have seen that, that's me. Fast, explosive, direct can get a goal, can assist as well, so I'm just looking to do more of the same this time round on a more regular basis."
