There was blame to share, but 2 of the 3 goals were the result of poor play by Vuk - and that doesn't include the own goal.
On the first goal he failed to track a Mukhtar run, allowing Dax to lob a pass to the box. Tinnerholm had to sprint to cover and stood up Mukthar with the ball. Vuk trailed into the box late and then, with a second chance, failed to slide effectively and block the shot (something we have seen Chanot and Callens do several times).
On the third goal he kept Sapong onside.
The own goal was tough, and another instance of a poor slide (similar to the first goal), but the biggest issue with that instance was Morales failing to stop the cross. Morales may be able to play with the ball in the back, and defend vertically, but he is poor at gauging crosses and defending horizontally.
Disagree on Tinnerholm. He covered miles, contributing on offense and covering for missed assignments from a makeshift back line. I have been underwhelmed by Malte most of the season, but I actually thought he was fine tonight. He helped clear a few messes in the back, and seemed to have a better sense of position.
I'll listen to an argument that Morales was the weakest link this evening - but I doubt it would convince me. And I am 100% fine if he is off the team next year.
More should have been done with the chances created, but there were chances created. Defense was the obvious issue that game, and Latinovich was the biggest contributor.
