Monaco produced a superb display to stun Arsenal 3-1 in their Champions League last-16 first-leg tie at the Emirates Stadium on Wednesday.
After a relatively slow start to the game, Geoffrey Kondogbia opened the scoring in the 38th minute before Dimitar Berbatov doubled the visitors advantage just after the break.
Alex Oxlade-Chamberlain pulled one back but Yannick Ferreira-Carrasco secured the win in the dying moments of the game while Bayer Leverkusen triumphed on home soil.
Roger Schmidt’s men will take a one-goal advantage into the second leg following a narrow 1-0 win over Atletico Madrid at the BayArena thanks to a venomous strike from Hakan Calhanoglu in the 57th minute.
The return leg will take place on March 17.
