The former Arsenal coach, Unai Emery, during his two-season stint in the French capital with Paris Saint-Germaine (PSG) won seven domestic trophies. He had to leave the club in 2018 after failing to live up to the ambitions of the PSG owner, President Nasser Al-Khelaifi, who is seeking a UEFA Champions League trophy.
Unai Emery, however, claims that his fortunes as an elite-level coach might have gone a notch higher had Video Assistant Referee [VAR] been in existence especially for the controversial match against Barcelona.
During an interview with France Football publications, he said,
"In Paris, I missed the chance to become the best coach in the world,
"I won the league, four domestic cups and two Trophees des Champions. But the ultimate goal was the Champions League.
"The first year, in the round-of-16 against Barcelona, were played a really high-level first leg. In the return leg, we were knocked out because VAR didn't yet exist. We were very clearly knocked out by refereeing decisions.
"The second year, against Real Madrid, we bowed to a team who recorded a historic hat-trick and, again, in the first leg, we could find fault with the officiating.
"To conclude: we lost the first time on refereeing decisions and the second against the defending and future champions."
During his first season in charge of PSG, they had thrashed Barcelona 4-0 in the round-of-16 first leg of the UEFA Champions League only to suffer an astonishing 6-1 defeat in the return match at Camp Nou, and that loss meant they were knocked out of the competition.
The following season, Emery guided the lads to the same stage of the competition (Round of 16) only to lose again 5-2 on aggregate this time, to Real Madrid, who thereafter won the trophy for the third season in a row.
