Manager Steve Robinson has secured the services of right-sided player Ryan McLaughlin on a one-year contract, with option of a further year.
The 21-year-old joins from Premier League side Liverpool and becomes Robinson’s 16th signing as Oldham Athletic manager.
McLaughlin can operate at both right back and right wing.
He is a full Northern Ireland international and has been capped at every international level from under 16 to the national team.
Robinson knows McLaughlin well and is delighted to get his signing over the line.
He said: “Ryan gives us something we haven’t got at the moment which is a bit of pace and energy out wide.
“He is a lad I’ve known since the age of 12 so he brings a lot of pace, energy and quality. He’s had a good grounding at Liverpool so we are looking for Ryan to make a big impact.
“He has only trained four days at this moment in time so he will be someone that we have to take gradually and not someone we can rush but he will be a very good addition to the squad.”
McLaughlin will number 27 during his time with the club.
