A combination of pictures created in London on April 2, 2018 shows Liverpool's German manager Jurgen Klopp (L) gesturing before the Champions League qualifier, second leg match between Liverpool and Hoffenheim at Anfield stadium in Liverpool on August 23, 2017 and Manchester City's Spanish manager Pep Guardiola (R) attending a press conference at the City Football Academy in Manchester, north west England on March 6, 2018, on the eve of their UEFA Champions League round of sixteen second leg football match against FC Basel. Jurgen Klopp has no qualms about saluting Pep Guardiola's ability to create "extraordinary" teams, but the Liverpool boss is convinced he can bridge the class divide when Manchester City visit Anfield for their Champions League showdown. Having first gone head to head with Borussia Dortmund and Bayern Munich, the friendly rivalry between Klopp and Guardiola has its biggest stage yet as Liverpool face City in the Champions League quarter-final first leg on on April 4, 2018. / AFP PHOTO / Oli SCARFF (Photo credit should read OLI SCARFF/AFP/Getty Images)
