The Serbian came from behind in his fourth round match against Lorenzo Musetti, with the teenager withdrawing from the contest with Djokovic 4-0 up in the final set.
Becker, who won six Grand Slam singles titles during his playing career, believes it is “advantage Berrettini” heading into the quarter-finals.
“Novak is a champion and he’s been in a situation like this before,” Becker said.
“He then reduces his emotions and the other guy starts thinking – ‘Oh, I can beat the number one in the world here’ – and in those five minutes he’s already lost the third set.
