Rafael Nadal’s loss in the fourth round of Wimbledon on Monday came as a surprise to many tennis watchers.

The Spaniard suffered a 3-6 4-6 6-4 6-4 13-15 loss in an epic battle with Gilles Muller from Luxembourg.

What was noticeable though was how irritated Nadal looked at times on court.

And it wasn’t really difficult to see why.

Just before they went out onto the court, Nadal bumped his head against a low ceiling while warming up.

It was just a first sign of what was going to be a bad day at the office.

He turned his ankle during the third set and was blinded by the sinking sun glinting against part of the Court One structure deep in the fifth set.

Fate truly seemed against him.
