European nights are a thing of folklore at Anfield from St Etienne in 1977 to Barcelona in 2019, but there is one Champions League game that Liverpool fans would be happy to forget.
Anfield was stunned into silence as Simao Sabrosa and Fabrizio Miccoli helped Benfica to knock out the holders in the last-16 in 2006.
16 years later the Portuguese side will be hoping to repeat the feat as they return to Merseyside on Wednesday.
Benfica face a tougher challenge to overcome a 3-1 deficit against Jurgen Klopp's men this time round but history has a way of repeating itself.
