With Gordon Strachan cutting back the club’s staff it seems highly unlikely that he will be able to take McManus to the Riverside Stadium on a permanent basis.
“I have no idea what happens, this is new to me,” McManus told the ‘Boro website. “I have never been on loan before, I don’t know what the scenario is.
“But what I do know is that I have really enjoyed my time down here, it’s really opened my eyes to life outside Glasgow. It’s been first class.
“Whether I go back to Celtic, somewhere else or I stay here I’ll be playing with a spring in my step and it’s because of this club.”
McManus added: “The fans have been great. When I came down here some had commented on the fans, some positive, some negative but personally they have been great.
“Plymouth really opened my eyes about the Boro fans. It was just incredible how many we took down there, especially in the circumstances. Players really appreciate that kind of support.
“I don’t think that enough people think about the men and women who work Monday to Friday and then pay good money to come and watch us. It’s an incredible feeling for us to wear the strip to make them proud.”
