你不是我对手英文

You are not my match

You are not my opponent 建议你去google的语言工具去查，这个工具还是不错的！！

you are not my opponent

You are not a match for me.

you aren't my opponent(敌人）

i am one too many of you .

以上的都是算对的，都是那个意思，但英文里没有那么说的如果是在和别人对立，说出这句话，可以说you are not my threat. or, you are no threat to me!

You are no match for me. You are not up to my level.
