French striker Odsonne Edouard, 21, put Celtic ahead with a classy finish in the 51st minute before substitute Scott Sinclair, on for James Forrest, added a third with a cheeky finish four minutes from time to put Lennon's side in the driving seat for next week's return game at Parkhead.

Johnston said: "If I keep performing well and I am training well, I will get opportunities.

"The manager has trusted me to play so I need to take a lot of confidence from that and scoring a goal helps.

"I worked myself a couple of yards of space and I just hit it. I am happy with it.

"I have scored some good goals so I don't know (if best), maybe.

"It was good to respond like that.

"When you are going away from home, it is always going to be hard.

"The boys dug deep and we got a result and that is exactly what we wanted to take back to Celtic Park."
