Demel has been first choice right back this season but he suffered a groin injury against Arsenal at the start of October and has only just made a return to first-team action.
Joey O'Brien has been impressive in recent weeks and kept his place in the side, despite the return of Demel who had to settle for a place on the substitutes' bench.
Demel said: "What is important is the team, so it doesn't really matter who plays. I am happy that the players in my position in the couple of games I missed did really well.
"It is good to have competition in the team and now I am just looking to get back to my best form and give my best when the coach and the team need me.
"It is always better to come back into a team that is winning, rather than come back in a team that is struggling.
"I tore my hernia, so I had to have an operation two weeks ago. After a couple of days we started the rehab and everything went really well.
“Last week was my first back in training and I got the opportunity to play 20 minutes, so I was very happy, though I need a couple more games to get back to my top form."
