“He’s changed me a lot and he’s brought a lot of confidence into me.”Now club captain, Osman credited Archibald with helping him to grow as a leader on the pitch and said that he still aimed to improve while helping Thistle achieve their goals in seasons to come.“I think I’m more responsible and I take charge more on the pitch,” he said. “Obviously the gaffer gave me the captaincy and that sort of thing I have to learn.“I’m striving to do that and do better.” “That gave me the go-ahead to extend my contract.”Osman is now coming to the end of his second season at the club and said that he was thoroughly enjoying life in Glasgow.“Ever since I’ve been here I’ve enjoyed my time,” he said. “There’s a good coaching staff and the boys here are brilliant.“Every day I come in I enjoy being here. I like the city but I think it’s most of all the manager.
