Brendan Rodgers has not ruled Kieran Tierney out of a second-leg appearance against Valencia in the Europa League.

Celtic host the Spaniards this evening in the opening leg of the tie, a game that has come too soon for Tierney.

However, while the Scotland internationalist will have to watch from the sidelines he could have a more prominent role for the return leg next week.

“That’s [the second leg] maybe a possibility but we’ll just test him over the next week or so,” said Rodgers.

“He’s looked very good in the last couple of days in training but he’s literally just re-joined the squad. There will be a point over the next couple of weeks when we can bring him in. He looks really strong but it would be unfair to bring him into a game of this magnitude after a week or so training.

“He’s desperate to play and that’s where he’s gaining experience because he also knows he has to look after his body as well.

“We’re desperate to have him back, but it’s just timing.”

Meanwhile, Rodgers has insisted that he has no qualms about Scott Bain making his European debut tonight if, as expected, the goalkeeper keeps the gloves ahead of Craig Gordon.

“What I love about Scott is his temperament, whether it was Ibrox in his first game, or at Hampden in the final, in front of 10 or 100,000 people,” said Rodgers. “He’s just one of those of those players who has a really good temperament for the game and he’s a fantastic goalkeeper.”
