A disappointing return of two points from their first three Group C matches leave Atleti's proud European record under El Cholo under threat
Atletico Madrid's achievements over recent seasons mean they must accept criticism for their current poor run, according to head coach Diego Simeone.
Under Simeone's management, Atleti have consistently performed above expectations – most notably in the 2013-14 season, when they beat heavyweights Barcelona and Real Madrid to title glory in La Liga.
Atleti were also beaten 2014 and 2016 Champions League finalists, falling foul of Real Madrid who also saw them off at the semi-final stage last season.
