Oldham have confirmed the appointment of Brendan Sheridan as an assistant to Matt Diskin.
He has been head coach at Dewsbury Celtic for the last few years, and led them to promotion to NCL Division Two earlier this year.
Sheridan told the club website: “Matthew took me through a full interview process. He sent me a video of an Oldham game and asked me to identify aspects of the performance in which improvements could be made on both attack and defence.
“I then met Matthew and Chris (chairman Chris Hamilton) separately for a scrum-down in which we discussed things like structures, criteria and, in Matthew’s case, what he expected of everyone. He will leave no stone unturned, that’s for sure.
“We had to make sure we were all facing the same direction and breathing the same air — that’s very important.
“A few days after the interview Matthew rang me and offered me the job and I told him there and then I was thrilled and delighted to accept.
“All my hard work in the amateur game over 12 years is now paying off and I can’t wait to get started.”
