The 2017 Miami Open has so far proved superb viewing for tennis neutrals.Six of the top ten seeds were dumped out of the competition before the quarter-finals, with form players such as Grigor Dimitrov losing out to ambitious unseeded adversaries like Argentina’s Guido Pella.Nonetheless, to some extent, an element of the old guard has shone through.Tenacious Italian Fabio Fognini is due to face the legendary Rafael Nadal in the first semi-final, while a blossoming Nick Kyrgios will take on one of the all-time greats Roger Federer in the second. Perhaps aided by dips in form from Sir Andy Murray and Novak Djokovic, Federer has been excellent in 2017, capturing his 18th Grand Slam title at the Australian Open with an impressive victory over long-term rival Nadal.The 35-year-old has cruised serenely through this week in Florida, defeating the likes of Roberto Bautista-Agut and Juan Martin del Potro in straight sets, to set up a last four encounter with Kyrgios.However, it was during his more testing quarter-final tie with Tomas Berdych that the Swiss produced arguably the shot of the tournament so far.Already 4-2 up in the first set, Federer only needed the first of two break points to widen his advantage over the experienced Czech.Having squeezed a flat forehand over the net, Berdych was rooted to the baseline as Federer lent into a loopy, but spin-laden, backhand drop shot.The crowd at Crandon Park Tennis Center certainly enjoyed Federer’s deft touch, while Berdych could only watch on in disbelief.See Federer’s wizardry for yourself in the video below!

As so perfectly described by @mmqallaf87, if Federer was an artist, this particular drop shot would be his masterpiece.

So perfectly executed and a simply stunning way to win the point.

Federer is yet again proving that age in sport is just a number, and that form is temporary, but class is permanent.

Let's hope the Swiss superstar continues to flourish throughout the season as we head into the French Open and then Wimbledon.
