No better candidate could suit the description more finely than Barcelona, who simply transcended to another level at the Camp Nou as they obliterated Roma. Hot on the heels of a Clásico thumping to arch-rivals Real Madrid, Luis Enrique's men certainly picked up from where they left off.
Luis Suárez initiated the rout just fifteen minutes in when the Uruguayan simply rolled it into an open goal after Neymar and Dani Alves worked down the right to set up their fellow South American. Some three minutes later and Lionel Messi, making his first start for the Catalans since September, while scoring a goal in the same proximity.
Barça's star-studded front three combined excellently which ended with the Argentine being through on goal and lobbing it over Szczęsny to really brush the Italians to one side. That was the prompt for cruise control before the hosts found a third, in spectacular fashion, right before the interval. Luis Suárez pounced on a defensive header to unleash a venomous volley into goal which just typified the limitless quality possessed by the men in red and blue.
With the hour mark fast approaching, Barcelona's party would continue. Piqué made use of his advanced position for a tap-in after Messi slid the ball across goal to the defender before the provider would bag his second, simply getting on the end of a rebound to place the ball past a devastated i Lupi defence.
It would soon be six, but only on the second time of asking after Neymar's penalty was parried out by Szczęsny, only for Adriano to get to it first and smash it into the net. Quite simply, a super six. Cameras weren't just out to witness Messi's magic, they also saw him give away a penalty in what seemed like an auspicious occasion. Džeko stepped up and was denied by Ter Stegen, although the Bosnian headed in for a consolation - if anything.
A resounding win for Barcelona reverberated around the continent, as a statement of intent is issued to all their contenders. With Messi back to fitness, and Neymar and Suarez showing no signs of letting up, it appears that the Catalan colours will continue to catapult into plenty of glory. Bayern Munich, however, made a good statement for themselves as the Bavarians made light work of their hosting of Olympiakos.
Within just eight minutes they found the breakthrough via the ever-shining star Douglas Costa. Compounding the Greeks with high pressure early on, Jérôme Boateng let fly from far out, stinging the hands of the keeper but Costa was on hand to sweep it away for the opening goal.
Robert Lewandowski's red-hot scoring streak would roll on albeit with a slice of luck as he got in the way of Müller's attempt but ever the poacher he placed it double the lead. Within twenty minutes it was a delightful three for Guardiola's army. Thomas Müller found the net through a simplistic tap-in after Robben headed across the face of goal.
It would be almost an eternity until Munich's next goal in comparison, but twenty minutes from time Kingsley Coman headed in Bayern's fourth to secure the points if they weren't locked up already.
What many regarded as the two favourites before the competition step up to the plate and raise the bar with complete performances. But over in England, looking to save the fate of English football lied in the hands of the capital's occupants, and both Arsenal and Chelsea did what was needed of them, and more.
With the Bundesliga champions nullifying Olympiakos on the same evening, Arsenal's hopes remained alie in a must-win game where they converted with an emphatic triumph at the Emirates Stadium. It all started with Mesut Özil's promising patch of form continuing as he died towards goal to guide it past the Zagreb keeper just before half-an-hour of play.
Wenger's International flare would continue to flex the muscle this time through the Chilean dynamite of Alexis Sánchez. They got the ball back from wasteful play by Sigali, allowing Monreal to set up the winger to double the lead some four minutes after his German teammate opened the scoring.
Sánchez got his second and Arsenal's third a while after the interval to set up a winner-goes-through clash with Olympiakos. Campbell cut in and sent the Chilean through finely to take it round the keeper and guide it into the net. With that, the jubilation around North London was juxtaposed by the nerves ahead of the match with Olympiakos where the winner will go to the knockouts.
Jose Mourinho had the pressure piling on him but as he searches to turn things around at Chelsea, Willian proves to be the spark again. But it wasn't just Willian - the Blues tore through Tel Aviv on a trip to Israel.
