Juventus defender Gleison Bremer says he's always trying to improve his defensive game.
Bremer is in his second season since his arrival from local rivals Torino.
He told DAZN: "(Dusan) Vlahovic is a physically strong striker, when we play together in practice matches I give him a lot of advice. He is good and is improving a lot.
"(Kenan)Yildiz is also a good striker, in training we go hard on him, but he doesn't complain and continues to play. He has great strength in his legs and can have a good career.
"There are attackers who can never be left alone, like (Victor) Osimhen and (Romelu) Lukaku, they are of international level. It is important to make the attacker nervous, because then few remain focused the whole time match.
"Defenders? There are many strong defenders around, like Virgil van Dijk. He is two steps above me because he won the Champions League and plays in a tough league like the Premier League. In the end, when a player retires, only the trophies won count, if you haven't won nothing you can't say you were the best."
