Juventus' Daniele Rugani the ultimate protege of Chelsea boss Maurizio Sarri
Under Sarri's guidance, Rugani played like a superstar. He was voted as player of the season in Serie B, as Empoli were promoted in 2014. He then proceeded to play every second of the 2014-15 season in Serie A, and didn't receive a single booking. That was an absolutely astonishing record for an inexperienced defender who represented relegation candidates, but Rugani's ability to anticipate his opponents' moves was sensational.
He compared to Gaetano Scirea, the most elegant centre-back Italy has ever witnessed. The youngster was very proud of that record.
"It is part of my style. I am more rational than others," he said at the time. "I use brains rather than instincts, trying to read the situation. I don't argue with referees and opponents too."
Rugani is a model professional -- it would be hard to find a more dedicated and disciplined footballer. At Empoli, Sarri had always praised him for being the first to arrive to the training ground and the last to leave.
