'I could do better. But honestly, that’s how I felt about 2015,’ Serena said in an interview to Wall Street Journal.
She won three Grand Slams and was stopped by the Italian Roberta Vinci in the US Open semi-finals. Her coach Patrick Mouratoglou thinks that Serena forgets the past. According to him, 'There are very few champions on this planet, and they share things in common.
One of those things is the ability to forget the past. They never look behind, always ahead.'
In 2001, she was booed by the spectators during the final, because Venus disappointed everyone by withdrawing from the semi-finals with an injury. The sisters had skipped the event thereafter until Serena made a comeback last year, saying that she wanted to be forgiving.
This year, Venus too participated in the event, after an absence of 15-years.
