Tuesday night was a bad one for Romanian outfit Steaua Bucharest after they succumbed to the full force of the Premier League when they hosted Manchester City.
Their Champions League adventure is all but over after the Citizens hammered them 5-0 in their own stadium with Sergio Aguero grabbing a hat-trick despite missing two – yes, two – penalties.
But, believe it or not, that was not the most humiliating thing to happen to the reigning champions of Romania, who were the victim of one of the most impressive pranks you are ever likely to see.
Fans from Steaua Bucharest's fierce rivals, Dinamo, somehow managed to infiltrate their 55,000-seater stadium, the Arena National, and lay down thousands of sheets of paper to make a mosaic – a tifo, as it is known – in the crowd.
The unsuspecting Steaua fans simply assumed the message would be in support of their club but when the players emerged from the tunnels, the tifo started to form the message “Doar Dinamo Bucuresti“, which translates as “Only Dinamo Bucharest“.
Take a look at the reaction below
But how did they do it?
As of this moment, the brilliantly elaborate prank has been given almost no coverage from around the web but 101GreatGoals claim to have found out exactly how it was executed.
They say a group of Dinamo fans contacted Steaua officials posing as professionals and offered their services to help prepare the mosaic ahead of the hotly anticipated Champions League tie.
Quite clearly, they managed to convince the club that they were a professional outfit meaning they were most likely paid for their services as well.
There is no way you can understate how big this is in Romanian football. Imagine Arsenal fans unveiling a Tottenham badge before a massive European game or the same happening with Everton at Anfield.
In fact, the rivalry the two Bucharest clubs share is, arguably, even more intense.
Things only got worse for Steaua when the game got underway with David Silva quickly giving Manchester City a 1-0 lead after 11 minutes. By that time, Aguero had already missed the first of his two penalties and later skied another.
However, the Argentine still managed to bag a hat-trick with goals in the 41st, 78th and 89th minute. New signing Nolito scored the other to make Pep Guardiola's passage into the Champions League proper a very simple one.
It is fair to say that the Steaua players won't be looking forward to the second leg at the Etihad, which is nothing short of a lost cause.
