Roger Federer has gone down in tennis history for his achievements, with a lengthy spell at number one among his stunning feats.
Jannik Sinner remains world number one despite continuing to serve his three-month ban, with Alexander Zverev and Carlos Alcaraz failing to capitalise on his absence.
Alcaraz has been too focused on Sinner’s ranking for his own liking, with the Spaniard currently third in the ATP rankings behind Zverev and the Italian.
He has been forced to miss out on the Madrid Open due to injury, with Zverev now aiming to create distance between himself and the Spaniard.
Sinner meanwhile can return on home soil at the Italian Open next month, just in time for another run at the French Open.

And that is a tournament in which he has very fond memories, having become world number one at Roland Garros last year.
It was, however, the Australian Open whereby legendary figure Federer clinched that ranking for the very first time.
The Swiss star beat Juan Carlos Ferrero in the 2004 Australian Open semi-finals, and would go on to hold the record for a stunning 237 weeks.

Unsurprisingly, Federer’s phenomenal tally has yet to be broken for players becoming world number one for the first time.
He finally gave up his spot in August 2008 to Rafael Nadal, although it wasn’t long until Federer made a return to the top.
But it was his 6-4, 6-1, 6-4 triumph over Ferrero that truly got the ball rolling, with the Australian Open second seed beating the third seed in straight sets.
Federer would go on to lift the iconic trophy in Melbourne, overcoming Marat Safin 7-6(7-3), 6-4, 6-2 in the 2004 Australian Open final.
