It didn’t feel like Arsenal had just qualified for only their second Champions League semi-final in 17 years. The final whistle came with overwhelming but cautious relief rather than ecstasy; the feeling that Arsenal had got away with one by the skin of their teeth, but next time they won’t be so fortunate.
Had Joao Simoes’s 94th-minute effort crept a few inches to the left, this last-eight tie was heading to extra time. That would’ve been catastrophic for Arsenal’s physical state ahead of their biggest game of the season on Sunday. In their current mental state, Arsenal progression would not have been a safe bet.
