But should he defeat Anderson, he will have his work cut out against a player who is tipped to be the successor to the relatively soon-to-be vacant throne of the Big Four – can Zverev begin the changing of the guard?

Becker was the last German to reach the final (Picture: Getty)For 37-year-old Federer, it was another disappointing defeat and he remains without a title at this event since 2011.

The German joked the media thought his ‘orehand was ‘absolutely crap’ ahead of this contest but it was anything but when he sent a stream of missiles in the Swiss’ direction, breaking to love to take the first set.

Federer responded quickly in the second, spanking a fierce backhand down the line to break but the young German hit back in an instant to level the second.
