Manchester City manager Pep Guardiola has been charged with improper conduct after he was sent to the stands by referee Antonio Mateu Lahoz during Tuesday's Champions League defeat to Liverpool, Uefa has confirmed.
City lost 2-1 at the Etihad Stadium due to second-half goals from Mohamed Salah and Roberto Firmino, which completed a 5-1 aggregate triumph for Jürgen Klopp's side.
Guardiola sent to stands for disallowed goal protests
Chasing an improbable comeback following a 3-0 reverse at Anfield last week, Guardiola named an attacking line-up and the hosts led on the night through Gabriel Jesus inside two minutes.
Wave upon wave of further attacks during the first half proved fruitless, however, and the City boss confronted his countryman Lahoz on the field at the break over Leroy Sané having a goal ruled out for offside. Replays showed Liverpool midfielder James Milner played the ball in the Germany winger's direction.
Guardiola's Uefa rap sheet includes two breaches of the organisation's disciplinary regulations - "dismissal from the bench" and "improper conduct of the coach" - meaning he could face a touchline ban in next season's competition.
Mateu Lahoz "likes to be different", said Pep post-match
Speaking to BT Sport after the match, the City manager spoke witheringly of Mateu Lahoz's officiating. "I said it [Sané's effort] was a goal. I didn't insult him, I was polite, I was correct. But Mateu Lahoz is a special guy, he likes to be different, he likes to be special," he said.
"I know what happened in Monaco last season, at 1-1, with an incredible penalty [not given to] Sergio Agüero. He's special. When everybody sees things, he likes to decide the opposite. I didn't say any wrong word."
Antena 3 reveals Pep's words
Spanish TV station Antena 3 revealed that Guardiola shouted at referee Mateu Lahoz: "That was a penalty, watch it on the tele. That was a goal and a penalty. Shut your mouth. That was a goal and a penalty".
Liverpool also hit with Uefa rap
Liverpool have also been charged as a club under article 16 (2) of the Uefa regulations in relation to fans setting off fireworks and throwing objects.
These charges were also levelled against the Premier League club in the aftermath of the first leg, when City's team bus was damaged by Liverpool supporters on its way to Anfield.
Charges from both games will be dealt with by the Uefa Control, Ethics and Disciplinary Body on 31 May.
