Fans have accused Atletico Madrid of employing ultra defensive tactics in what has been a one-sided UEFA Champions League quarter-final first-leg tie between the Spanish side and Manchester City.The ball has rarely left the Atletico half of the field, with City continuously trying to break down the La Liga side. City fans aren't pleased with how Atletico Madrid have set up, accusing the reigning Spanish champions of deploying a '10-0-0' formation.In years past, you would not have associated a Spanish side with setting up in the manner they have, which is more similar to that of a defensive Premier League team.But Diego Simeone's men have left no gaps between defenders with Manchester City looking increasingly irritated by the difficult task of breaking through the defense.Fans watching are also seemingly irritated by the formation deployed by the Spanish side and have reacted on Twitter:Elvis Tunde ➐@TunnykvngAtletico Madrid have taken this satanism football to another level #CheersToPassion #CheersToAllFans8:33 PM · Apr 5, 2022398102Atletico Madrid have taken this satanism football to another level 😂#CheersToPassion #CheersToAllFans https://t.co/txYPgLBsXy🇫🇮@EetuAntxroI’m convinced that Atletico Madrid fans don’t enjoy football after watching terrorism football for over 10 years.

Simeone's side have looked dangerous each time they've broken against the run of play.With Joao Felix and Antoine Griezmann up front, there is always the risk of being hit on the break.The duo have looked lively when in possession, which has been a rarity, so City will need to ensure that they're not vulnerable whilst putting pressure on the Atleti defense.But every Atletico Madrid player looks assured, they know their role and they are keeping the Cityzens at bay.Atletico knocked City's neighbors Manchester United out of the last round in what was a similar sort of set-up during the second-leg.Manchester City will be wary of the way in which the tide can just suddenly turn, with Simeone a master in stealing a victory.At the time of writing, both teams are still locked at 0-0 with just under 30 minutes of normal time left at the Etihad Stadium.
