For just £11m this summer, Arsenal signed Bayern Munich’s kryptonite.

Back in 2012, in Bayern’s own stadium, Čech somehow denied them time and time again to win the Champions League for Chelsea. The goalkeeper saved an Arjen Robben penalty in extra-time, before saving two penalties in the penalty shootout.

Thankfully for Arsène Wenger’s side, he was at it again on Tuesday night. Čech made an incredible save in the first half to prevent Thiago from giving Bayern the lead, and his general composure made Arsenal looked relaxed all night long.

There were no fumbles, no slips. Everything was made to look pretty straightforward and unspectacular, and what a difference that makes to the entire team. When called upon to produce something more out of the ordinary, Čech always delivered. Bayern rarely troubled him as Arsenal were organised enough to prevent them from having big chances, but he was called upon to keep us in the game twice and did so with no fuss. The save from Thiago was good, one from Lewandowski was even better.

Big saves at big moments, from another big Arsenal signing. There should be little doubt over who will start in goal in Arsenal’s next Champions League game.

To top it all off, Manuel Neuer dropped a clanger to gift Arsenal the opening goal. Čech is no frills, but that means no errors. Neuer’s style is high risk high reward, and nobody can alway get it right every time. Čech not only makes great saves (which, to his credit, Neuer did) but is much steadier, and it paid off on Tuesday.
