The young team will play against their Irish counterparts tonight at New Douglas Park and Caddis feels that playing against tougher opposition may convince the Manager to add to the player's five first team performances this season.
He said: "Every game you play you're going to be watched, so you want to impress. Playing in international football you are playing against the best, so it's a chance to impress my club manager.
"It's pleasing to get a chance at Celtic but it is difficult at times as well. I need to keep working hard and keep getting these games but everyone is trying to do that at Celtic. I have top-class players ahead of me at Celtic so I've got to be realistic and work on certain aspects of my game.
"The manager has shown faith in me by putting me in big pressure games, so I know I need to keep working hard.
"Being versatile is good and the manager knows I'm available to play in either full-back positions or on left or right midfield. I'm happy to play anywhere."
This kind of willingness to play in any position will surely give the player more hope of forcing his way into the Managers plans, and with the rise in form of Andreas Hinkel it may be longer before we see young Paul in his preferred position at right back.
Yours in Celtic
