While it is very disappointing to go out so tamely, I don't think that enough credit has been given to Aberdeen for setting up in a way to stifle our attacking threat. I have endure re-watching the game without the tension of live coverage
All of our width tends to come from our wing backs and by playing Hayes, McGinn, Pawlett, Rooney and Stockley, the wingbacks were not allowed to get forward and the 3 central defenders were all pinned back so that they couldn't support the midfield either. As result we had no width and were outnumbered in midfield where their 3 at the back could step up with only Doolan to watch out for. How many times did we see Abdul as our wide man ? A good player, but not his best place.
Aberdeen also pressed high up the pitch. so we never had any time to settle in possession. We were second to every loose ball and lost most of the 50-50s which is not like us in recent games.
What I didn't appreciate at the time is how well we dealt with their attacking 5. Cerny did make a couple of good saves, but for a home side they didn't create very much either. The goal came from Booth losing his foot in the surface which gave Shinnie that yard to turn and get in his shot. He took it well, but normally our defense would have had an extra man available as cover.
As for Abdul's header, It was not a sitter, but you would have expected him to hit the target more often than not. It would be interesting to know what would have happened if he had left it for Keown behind him who looked to be even better placed.
