Champions League football never fails to entertain and that was once again the case during Tuesday night's fixtures.
English clubs Liverpool and Manchester City were in action against Spartak Moscow and Shakhtar Donetsk respectively, though only one emerged victorious.
While Liverpool slumped to a disappointing draw in Russia, City made it two wins out of two in Group F with a 2-0 victory.
Elsewhere, in Group H, Tottenham ran riot against APOEL FC thanks to a Harry Kane hat-trick and Real Madrid beat Borussia Dortmund 3-1.
Gareth Bale and Cristiano Ronaldo (2) both got themselves on the scoresheet, with Bale's 18th-minute opener the pick of the goals.
From Dani Carvajal's cross, the Welshman rifled a volley into the top-right corner, giving goalkeeper Roman Burki absolutely no chance.
However, one of the biggest stories to emerge from Tuesday's set of games came from Besiktas' 2-0 win over Bundesliga side RB Leipzig at the Vodafone Arena.
Goals from former Liverpool ace Ryan Babel and Talisca secured all three points, but the standout moment from the game came on the half hour mark.
In rather bizarre circumstances, striker Timo Werner signalled to the bench that he wanted to come off despite not carrying an injury.
It turns out that Werner was struggling with the noise Besiktas' fans were making and couldn't bear how loud it was on the pitch, per the Telegraph. Check out the video below.
Werner was clearly in some discomfort and after trying ear plugs had no choice but to request a substitution. Never before has a player been forced to retire because of too much noise.
There are rumours that Werner was suffering from something called Vertigo, which the NHS describes as "a symptom, rather than a condition itself".
"It's the sensation that you, or the environment around you, is moving or spinning.
"This feeling may be barely noticeable, or it may be so severe that you find it difficult to keep your balance and do everyday tasks."
Vertigo is brought on by a balance issue in the inner ear, which in Werner's case can't have been helped by the loud cheering from Besiktas' rowdy fans.
Hopefully it's nothing too serious.
