Pep Guardiola has suffered a setback before a ball has been kicked between Manchester City and Liverpool, after Antonio Mateu Lahoz was appointed to referee the second leg of their Champions League quarter-final clash.
Guardiola has not forgiven Spanish ref Lahoz for his performance when City crashed out to Monaco last season, and brought it up after they lost 3-0 at Anfield on Wednesday night.
The City boss was furious 14 months ago when Sergio Aguero was taken down by Monaco keeper Danijel Subasic, but Lahoz booked Aguero instead of awarding a penalty.
