Manchester City manager Pep Guardiola blasted Spanish referee Antonio Mateu Lahoz and lamented a number of decisions that cost his side dear after a 2-1 home defeat by Liverpool on Wednesday sealed a 5-1 aggregate Champions League quarter-final win for the five-time European champions. Guardiola was forced to watch the second half from the stands after being sent off for his protestations at the break as free-spending City's dreams of conquering the Champions League for the first time were dashed for another season. City led 1-0 on the night at that stage after Gabriel Jesus's second-minute opener, but the hosts felt aggrieved after Leroy Sane had a second goal wrongly disallowed for offside just before half-time.
