Celtic's Mikey Johnston admits any playing time he gets is a "bonus" after his return to fitness.

The tricky winger netted within a minute of coming on as a sub against Ross County and was delighted to also score against Rennes last week in his first game since September.

Johnston, 20, is smart enough to understand it's going to take time for him to break into the starting XI for a consistent spot on the pitch with the competition in the Celtic squad.

But he's willing to bide his time and will be content with any game time thrown his way.

"Being injured was tough. It’s part of football and something everyone has to go through at one point," Johnston said.

"You have to keep your head down, keep your mentality strong and come back.

"I’m just trying to work hard and get my fitness up. Any minute I get is a bonus.

"It’s always going to be a bit more seamless to come back if the team’s playing well and as a forward to try and get goals.

"I know what my role is as a player. I need to contribute goals and assists and do my defensive duties to help the team as well.

"We’ve got loads of good wingers at the club that I can learn from with experience in the game. If I can take a little bit of their game and add it to mine, then great."
