Help me talking with a lol celebrity pls!!

Hey, so basically I met a guy in LoL that knows a famous player, and... That player lost yesterday a VERY important series (LCS Finals). I talked so much with the guy that knows him and... I would like to say something to him that he can say to that player to cheer him up. Which would be the best sentence to cheer up a proffessional player? Thanks guys :D

(Sorry for my bad english btw Im spanish xD)
