Powell was snapped up from Crewe Alexandra last month.
He told mnautd.com: "Itâ€™s been great. The lads are really nice and theyâ€™ve all helped me through the first week. I feel like Iâ€™ve fitted in well with everyone. The training is different but itâ€™s something Iâ€™m enjoying and just getting used to.
"Walking into the dressing room and seeing my name on my peg was a great feeling and the first people I saw were Giggsy and Scholesy. Iâ€™m just used to seeing them on TV so it was pretty amazing to see them stood there. They came over straight away and welcomed me which was great.
"Iâ€™m really looking forward to playing and training with them - Scholesy is a midfield maestro and one of the best in the world ever and then youâ€™ve got Giggsy who has been running the left wing for over 20 years."
