Little impressed the management team in a trial which begun a few weeks ago, and thoroughly enjoyed the experience of travelling to two countries with the Blades. Pre-season has been so enjoyable for the 33-year-old, he confesses that he feels like he's 'been here for years'.
He said: "I'm looking forward to the challenge, I've had a pretty good pre-season. I'm really looking forward to the season beginning as I haven't started one for about four years. I've been injured at the start of the past few campaigns which has hampered me, so I just can't wait until Friday night.
"We've got a great opener against Middlesbrough, a team that has just come down from the Premier League, we're live on Sky, so I am looking forward to it.
Glen was released by Reading a couple of month ago, and he was delighted when he had a phone call from Blades assistant boss, Sam Ellis, enquiring if he could endure a two-week-trial.
He continued: "I spoke to Sam in the summer and he said, 'come up and have a good pre-season and see how you get on', so yeah it's been great and I've settled in with all the boys.
"It feels like I've been here for years with the good bunch of lads.
"I know Sheffield United are a tough team to play against. I've had a good few battles with them and they always have a strong squad. Last season they had a good season but unfortunately, it doesn't always go your way."
United have plenty of options on the wings now, with the likes of Keith Treacy, Kyel Reid and David Cotterill all fighting for a starting-berth, and Glen knows he's not going to play in every game.
He finished: "I've spoke to the gaffer and he told me that I might not be playing every week, and he may just save me for certain games here and there, so that's fair enough. The Championship is very demanding, and I am at that age now where I might not be able to play Saturday, Tuesday, Saturday, but the gaffer has plenty of options who can offer their contributions too."
