[PC]Met a hacker in Champions Finals and he somehow crashed my client.

Met a hacker, again, in Champions finals and he did that stupid thing where all you players are unable to run. after he scored his first goal, he got my client to crash. This is getting very  frustrating. I have reported the player via the website but it puzzles me that you can't do it in game.  This also means i can't finish the 15 played games now due to the hacker. 

What can i do ?
