One accusation that has regularly been levelled at Neil Lennon and his Celtic coaching team is that they’re not coaching players properly.
It is often suggested by fans that the Hoops gaffer takes a laissez-faire approach to training and player development.
The idea goes that Lennon is a motivator, rather than an improver.
But Jeremie Frimpong’s performance on Thursday night shows there is plenty of work being done in the background at Lennoxtown.
The young Dutch full-back was his energetic self in the 2-2 draw with Lille. But with one key addition. An end product.
Frimpong got his head up in Lille
Frimpong will be world-class if he can ever find a final ball to match his incredible acceleration and sprint speed.
He regularly finds himself in promising attacking-third positions only for his delivery or passing to let him down. France may have been the start of a change on that front.
Frimpong registered an impressive assist for Mohamed Elyounoussi on Thursday, and also sent a tantalising ball in for Albian Ajeti shortly before.
On both occasions the full-back, still only 19, got his head up. That was the key difference.
Taking a pause and getting his head up is something that Frimpong has clearly been told to work on at Lennoxtown.
This small, but crucial, improvement is a clear example of Celtic doing some positive work on the training ground.
If the coaching team have identified a weakness in the former Manchester City youngster’s game then they’ll be doing likewise with his team-mates.
It all bodes well for the future.
