Celtic's youngsters looked on course for a significant victory over their Manchester City counterparts in this afternoon's Uefa Youth League encounter, but let slip a 2-0 lead to lose 3-2.
Give us your thoughts on today's Scottish football news.
Is Ian Cathro the right man for Hearts?
Can Celtic get a result this evening against Manchester City?
Will Aberdeen get back to winning ways this evening or can Kilmarnock gain revenge for their 4-0 drubbing at home to the Dons in October?
Ian Cathro wants to push the boundaries of what Hearts can achieve after being appointed the club's head coach.
The 30 year-old succeeds Robbie Neilson and wants to build on the work that established Hearts as a top four side.
Cathro has no playing or management experience but insists there will be no issues with being the voice of authority in the dressing room.
"There isn't a limit to what you can do unless you believe in limits everybody else has set for years," he said.

From Pep Guardiola to Zinedine Zidane, the herograms for Moussa Dembele keep flooding. All manner of global footballing icons have praised the young Celtic striker to the high heavens, a slightly surreal but totally understandable reaction given what he was done with his club and with the French under 21 side.
In all of this, it's worth considering the man he has displaced at Celtic Park - Leigh Griffiths. It only seems a relative blink of an eye ago that Griffiths wasn't just The Man at Parkhead, but The Only Man. Forty goals last season and eight in his first 10 appearances this season, Griffiths carried the goalscoring burden - and he carried it lightly.
He has nine goals so far this season. At this point last season he had 18. Injury robbed him of his place in the team in late August and Dembele's excellence has kept on the sidelines. Since returning from a month out, Griffiths has started just two games for his club, albeit both of them were recently. Of the truly big games, he played just six minutes against Manchester City, 19 minutes against Borussia Monchengladbach, 20 minutes against Rangers and one minute against Aberdeen.
This is a challenge for Griffiths but also for Brendan Rodgers. How does he keep his second striker happy and sharp and confident? There will come a point when Dembele is tired or injured or just out of sorts. After so long in the wings, can Griffiths just slot back in and be the player he was before? He thrives on involvement. He's been totally professional, but deep down he must be a hugely frustrated player right now. He has to be wondering when he's going to nail down a starting place again.
You wonder what Rodgers is thinking ahead of tonight's Champions League meeting with Man City. Does he continue with Dembele, who scored twice against City in Glasgow, or is this one for Griffiths - a European game to get his mojo back? Rodgers has two class strikers, but their stories are in stark contrast so far this season.
Meet Austin MacPhee, who will be right-hand man to Hearts head coach Ian Cathro.
He talks of having "synergy" with Cathro, but not complete synergy, so they won't be afraid to challenge each other's thinking.
Their reign begins versus Rangers at Ibrox on Saturday.
If our calculations are correct, Don Cowie will be the only current Hearts first-team player older than the head coach.
Cowie is 33 and the new boss Ian Cathro is 30.
- Aberdeen have won each of their last 11 Scottish Premiership contests against Kilmarnock, scoring 23 and conceding just four.
- Killie’s last win against Aberdeen came in December 2012, winning 2-0 at Pittodrie thanks to two goals from Liam Kelly.
- None of the Dons’ last nine league games has ended level, with Aberdeen winning six of those and losing the other three.
- Kilmarnock are looking to win consecutive top-flight games for the first time since October 2015.
- Adam Rooney scored twice in Aberdeen’s 4-0 win over Kilmarnock in October.
- Half of Kilmarnock’s goals this season in the Scottish Premiership have been scored by Souleymane Coulibaly (7 of 14).
