Progress to the quarter-finals of the competition that made Unai Emery’s reputation, the Europa League ­continues to offer ­sanctuary for Aston Villa. The second leg was completed without too much drama, via the ­welcome sight of John McGinn scoring a fine goal. Villa have sorely missed him, though the ­contributions of Emi Martínez, in making a save then launching an attack, and Jadon Sancho were crucial to clinching the tie.
