Absolutely no need in that last bit, calling someone clueless due to a difference of opinion.
Gallagher was immense for Scotland in the two qualifying games but I hadn't been convinced by him for Scotland before then, thought he was poor in his first couple of internationals. He was also no doubt helped a lot by the quality of players around him and the fact that his role was basically just to win headers against mitrovic.
I've seen plenty of evidence this season to support the idea that his game against Serbia was a well above average performance for him. He's been the direct cause of several goals Motherwell have conceded this year. He also cost them their Europa tie with two stupid errors in the space of 5 minutes when it was looking like they could put out a strong Israeli side.
