With their season on the line, Arsenal’s players produced a devastating first-half performance on Thursday to beat Slavia Prague and reach the Europa League semi-finals.

They’ll meet a familiar face there. Arsenal’s 4-0 win in the Czech capital—secured courtesy of a three-goal burst in six minutes from the 18th—clinched a 5-1 aggregate victory and set up a Last Four match against Villarreal, which is managed by Unai Emery. The Spanish coach spent an underwhelming 18 months at Arsenal as Arsene Wenger’s replacement in 2018-19 and is rebuilding his managerial career at Villarreal, which beat Dinamo Zagreb 2-1 and advanced 3-1 on aggregate. Manchester United and Roma complete the semi-final lineup.
