James Forrest's goal in the Scottish League Cup final was yet another example of how far he has come under Bhoys boss Brendan Rodgers.
The 26-year-old is now one of Celtic's most influential stars and one wonders how much of that is down to the ongoing presence of Patrick Roberts.
After all, the Manchester City youngster was outstanding for Celtic last season, but this time round he is struggling to start and much of that is down to Forrest's own superb form.
Forrest has slowly and impressive grown into a consistent performer under Rodgers and he is now surely one of the first names on the Celtic team sheet.
That is not good news for Roberts, but the younger man's presence and undeniable talent is likely to have been another motivating factor for Forrest, who does not want to lose his place to a player who will not even be around next season.
Forrest is reaching his peak in his mid-twenties and it will be interesting to see if he can get even better over the next couple of years, with or without the challenge of Roberts.
Celtic have a fine squad and a brilliant manager and with a little more luck they could yet make real waves in Europe, with Forrest likely to be integral throughout.
