Porto boss Sergio Conceicao has launched a stinging criticism of Manchester City counterpart Pep Guardiola and claimed he used 'ugly words' on the touchline during their Champions League group game fixture.
The duo were seen arguing on the touchline on several occasions during City's 3-1 win against the Portuguese side over a number of refereeing decisions.
Guardiola played down the incidents after the Group C encounter, claiming he and Conceicao are 'friends', but the Portuguese has not reciprocated and instead ripped into the former Barcelona boss, accusing him of putting pressure on referees and having a poor attitude.
