Arsenal head coach Unai Emery is regarded as an expert in the Europa League.
The Spaniard won the competition three times in a row when in charge of La Liga outfit Sevilla - coming from behind to beat Liverpool in the 2016 final.
It's certainly an impressive achievement, although former Manchester United manager Sir Alex Ferguson once took a sly dig at Emery for his constant presence in the competition.
"One day we were in Nyon for the coaches meeting and I was defending a lot the Europa League, and he – Ferguson – asked me, 'But really Unai, do you not prefer to win the Champions League?' Emery told Soccer AM .
"Yes of course! He didn’t need to say it! But at that moment I can be happy and I can defend the Europa League because also I think the UEFA people improve a lot this competition.
"But really, really the first is the Champions League – okay.
"My first trophy was the Europa League with Sevilla, against Benfica in Turin. It was amazing.
"As a player it was very difficult to achieve some trophies, when I was starting as a coach I was thinking, 'I want to progress, I want to improve, I want to move ahead' and when the first title arrived it was [breathes sigh of relief].
"And really after continuing winning some more and really I am here and my objective is to achieve some important things in the football first, and after is to achieve titles."
It proved to be fourth time unlucky for Emery in his first season as Gunners head coach as his side were beaten 4-1 by Chelsea in the final in Baku, Azerbaijan back in May.
That loss means Emery will have another chance at Europa League success this term.
Arsenal have been drawn in a group alongside Eintracht Frankfurt, Standard Liege and Vitoria.
