Everything is left to play for in next week’s UEFA Europa League quarterfinals second leg, but Thursday’s action put a few teams in prime position to advance to the final four.
Ramsey’s second — a superb back-heel finish in the first half — helped put the Gunners ahead 3-1, before Lacazette’s second goal extended the home tie to 4-1 just minutes later.
Meanwhile, Atletico Madrid and Lazio each earned comfortable home wins, setting the Spanish and Italian sides, respectively, up to advance next week.
Atleti took the lead in the first minute of action when Koke gave the La Liga side the advantage, before Antoine Griezmann doubled the lead prior to halftime.
The closest finish on the afternoon came in Germany, where Red Bull Leipzig pulled off a 1-0 win over Marseille behind Timo Werner’s first-half stoppage time goal.
Arsenal 4-1 CSKA Moscow
Atletico Madrid 2-0 Sporting Lisbon
Lazio 4-2 Red Bull Salzburg
Red Bull Leipzig 1-0 Marseille
