Berrettini still behind Sinner: "He's paying for a mistake".

Jannik Sinner's three-month suspension for doping continues to cause a stir in the tennis world. His compatriot and friend, Matteo Berrettini, reacted to the suspension.
For him, what happened to Sinner could happen to anyone.
He says: "I've always supported Jannik and I won't stop now. I think this is a very hard time for him; he's paying for a mistake and I feel sorry for him.
I'm not a lawyer, so I don't know the details, but I have no doubt that he'll come back stronger.
The subject is complex. It's difficult, if not impossible, to control everything. ATP helps us.
For example, when we go to play in certain countries, they advise us by e-mail not to eat red meat which could be contaminated.
We've always been used to being extremely careful, but things can always happen that escape our attention."
