McGinty, 20 was a number of players released by the Blades this summer despite spending just one season at Bramall Lane having been brought in by David Weir from Manchester United. He made just 3 appearances in red and white colours and in March joined The Dale on loan where he played just once.
Rochdale assistant manager told rochdaleafc.co.uk; “I know the supporters didn’t get to see too much of Sean on a Saturday (while on loan), but Sean comes from a great stock of pedigree after being at Manchester United from the age of 14. He has impressed us in the way that he went about his training, he impressed us in how he went about supporting the squad on matchdays, whether he was getting changed or not.
“He’s got a very good left foot, he’s of good stature, he’s of good size, he’s still got lots of potential, so it fits us. I’m looking forward to seeing how he goes about pre-season and the way that he’ll step on to that good work that he did during his loan period.”
