I am reading this article,
I have a problem understanding this sentence:
What doesn’t kill you makes you stronger. The famous words that perhaps best describe players who wear Azzurri shirts on the international stage. For the current generation of strikers in and around the Azzurri team, the only way is up.
what does up means in that context please?
Does it mean that the current Italian strikers are good? or the current Italian strikers must be good? or something else?
