Arsenal will play Villareal in one of the Europa league semi finals after overcoming Slavia Praha 4-0 on the night and 5-1 on aggregate .
Alexander Lacazette scored twice and Pepe and Saka got a goal each to complete the win.
It kept alive their hopes winning the competition and with it their only realistic chance of European football next season.
“The boys were really at it from the start,” Arteta said. “We won in a convincing way, so credit to the players.”
It is 25 years since Arsenal, currently ninth in the league, failed to qualify for Europe and this win ensured they can extend that run.
A meeting with Emery, who took Arsenal to the Europa League final in 2019 and won the tournament three times as manager of Sevilla, awaits on 29 April.
Villareal on the other hand beat dynamo Zagreb 2-1 to finish a 3-1 aggregate win.
In the other semifinal Manchester United beat Granada 2-0 to set up a date with Roma who defeated ajax 3-2 on aggregate.
United won the Europa League in their last final but have lost all four semi-finals in which they have featured during Solskjaer’s reign, including in this competition last season.
Their progress to a fifth was never in doubt after Edinson Cavani provided a smart finish to Paul Pogba’s sixth-minute flicked header to extend their aggregate lead to 3-0, after a two-goal win in Spain last week.
As Roma came through a nervy night at the stadio Olimpico against Ajax, it means a reunion for United old boys Henrikh Mkhitaryan and Chris Smalling, who has been sidelined in recent weeks with a knee injury.
