There were a few, but it really wasnt anything terrible. Mandzukic(?) had a hard collision with the keeper, he was definitely hurt, and he was the only one really "wasting time", which btw the ref let them play on just fine for the most part.
The fact is england got almost complacent after the first half. They were outworked massively in the midfield by croatia, and didnt push hard enough to create opportunities even after fatigue had clearly hit croatia first. It wasnt until they were down to ten men with like 3 minutes left in extra time that they actually put the pressure on and it was just too late. And croatia only even scored the second goal because the england defense literally stopped paying attention during a 50/50 ball right at the top of the box. Croatia deserved every bit of this win
