I was reading an article about a football manager talking at the end of a match:
"So ist Fußball. So ist er gut. So ist er toll."
I know that so is a complicated word in German, but for the sentence
So ist Fußball
I thought so meant "That"
So ist er gut
I thought it meant "That is good."
But what is the purpose of er in that sentence.
What purpose does it serve?
