It was far from the most entertaining performance you’re likely to see from Neil Lennon’s side this season, but in the end it doesn’t matter, they are into the next round of the Europa League.
Heading for the slog of at least another 30 minutes with extra-time, two substitutes combined to win the game for the visitors.
Jeremie Frimpong sent in a low cross and Mohamed Elyounoussi was there to sweep the ball into the back of the net.
They were two players who got strong marks in our player ratings, but what about the rest?

2. Nir Bitton - 7
Did well to stop an early three-on-one and looked more assured than his centre-back partners. Photo: Craig Williamson - SNS Group
3. Kristoffer Ajer - 5
Didn't have much to deal with and still looked rather uncomfortable throughout. It was his mistake that led to the three-on-one. Photo: Craig Williamson - SNS Group
4. Shane Duffy - 5
He's not at Celtic for his ability on the football and he showed that here. Decent in the air but very poor in possession. Photo: Craig Williamson - SNS Group
