Novak Djokovic continued his stunning form on Wednesday night with a demolition of Stanislas Wawrinka 6-3 6-0 at the ATP Finals, just days after doing the same to US Open champion Marin Cilic, and the world no.1's most recent virtuoso display was witnessed by two Arsenal footballers.
The Gunners' season has already suffered an early derailment thanks largely to a high volume of injury to key players, and two of the prime examples of this took their place in the O2 Arena as they continued their recovery.
As you can see from the image above; striker Olivier Giroud and defender Mathieu Debuchy, both French internationals, turned their mind to another sport for the evening.
I guess it's quite handy for the pair, whilst injured, who play for the North London side, to have the ATP Finals taking place in the same city that they ply their trade in, even though it may be a tube journey away.
Arsenal have quite an affinity with tennis at the moment. Last year the likes of Jack Wilshere, Mikel Arteta, Lukas Podolski and Per Mertesacker who represented their clubs. Roger Federer repaid the visit in the lead-up to this year's event when he watched the club's home Champions League match with Anderlecht.

Meanwhile Debuchy and Giroud wren't the only high-profile names from outside tennis to enjoy the competition from the past week, as disappointing as it has been thus far. Liam Payne from boyband One Direction took his girlfriend to watch Andy Murray the previous night.
However, one man who doesn't take into account the whims of London-based professional footballers and celebrities is Djokovic himself. The Serb has been saying recently how he thinks the season-ending tournament should move to another city after 2015 when the O2 Arena's contract expires.
London faces a battle to keep hold of the Finals, facing pressure from venues in China and other Asian countries to secure a lucrative contract, and the 27-year-old believes somewhere else should get the chance to play host.
DJOKOVIC LOVES THE O2 ARENA
The English capital has been kind to Djokovic in recent years, the seven-time Grand Slam champion has won the past two tournaments - whilst remaining on-course for a hat-trick this year - though he also won the last competition to be held outside The O2, back in 2008, when Shanghai was the focal point.
"This tournament here in London has had an immense success. London has proven to be one of the best cities for tennis. People have a culture of tennis here because of Wimbledon," Djokovic admitted after beating Wawrinka.
"But I believe that this World Tour Finals is a kind of tournament that should be, I would say, exposed to more cities around the world. We should allow more cities to have the organisation of this event, the best eight players in the world. In this way we can promote the tennis in certain areas.
TIME TO MOVE ALONG?
"Now I understand the different points of view, different perspectives, people have different opinions. I understand they keep it here because of the success. But, again, I heard many cities who want to not just pay big money to have it, but also have a big interest.
"I'm sure that many cities around Europe, South America, Asia, would have a lot of success in having this event.
"Me, personally, again with nothing against London, I enjoy this tournament very much, and as I say it's a success, but it should be moved more often."
Maybe Djokovic's opinion will change if he can bag yet another Finals title by Sunday, he remains the favourite and it's easy to see why as he has only dropped a meager five points in two matches.
