Yea, Fred oversold the grab and didn't deserve the penalty. I don't know about Olic's call becuase the ref probably wasn't in the right angle to see it
Some would argue that Neymar was the MOTM but I think Oscar deserves it in my opinion. Croatia got dangerous in the last 5 minutes but their centre backs looked confused. I also don't know what they were trying to get out of large guys in the front positions
