Arsenal’s 2-0 win at Monaco wasn’t enough to overcome a 3-1 defeat in the first leg. But 
according to Arsene Wenger, Monaco didn’t deserve to go through, since the away-goals rule is an outdated relic of the 1960s. “Two Premier League teams have gone out on away goals and that should be questioned,” he said. Because if a rule hurts English teams, it must be a bad rule.
But here’s the thing: Arsenal’s recent Champions League struggles – five Round-of-16 eliminations in a row – have less to do with the away-goals rule than with the team’s inability to play consistently over the course of a two-legged tie. Arsenal has a long history of capitulating in the first leg, only to mount a courageous, but ultimately futile, comeback two weeks later. In 2012, Arsenal lost 4-0 to AC Milan at the San Siro, and then won the return game 3-0. A year later, having lost the first leg 3-1, Arsenal beat Bayern Munich 2-0 in Germany. Indeed, Wenger’s team has lost just one second-leg game since 2011.
“You can’t win a tie in the first leg, but you can lose it,” or so the old cliché goes. Arsenal routinely loses its Champions League knockout ties in the first leg. And Wenger, who’s paid to motivate his players and plan the team’s tactical approach, has no one to blame but himself.
