Commons urges Celtic to fire up for CL qualifiers
The Hoops have been beaten in all three of the offseason fixtures thus far but Commons is determined to put that right when they tackle Northern Irish side Cliftonville at Solitude on July 17 prior to the return leg in Glasgow the week after.
"With players being away on international duty it's meant they are all coming back in dribs and drabs," he told the club's official website. "It's been a little strange and as a result we've not had much time to prepare ahead of our matches.
"We're not performing as well as we should be but hopefully we will start turning the corner now.
"As a professional you need to practise what you take into a game. Some people assume that because we are paid to play, we can go on to the park and everything just falls into place but behind the scenes you have to work really hard and spend a lot of time on the training pitch and in the gym.
"I do believe that when the Cliftonville game does come around our lads will be fully focused and the lights will go on for the big game. After that we will be bang up to speed."
