An Arsenal goalkeeper did the unthinkable against Östersunds FK on Thursday night: they saved a penalty.

Petr Cech hasn’t saved a single spot-kick since he moved to Arsenal from Chelsea in 2015 and, at this rate, it’s looking like he never will.

Perhaps this is why David Ospina has now become a hero among fans for his penalty-save against Östersunds FK in the Europa League.

Although Arsenal were dominating the Swedish team comfortably by this late stage, when Shkodran Mustafi shoved Saman Ghoddos down in the area, fans felt sure their first clean sheet since the draw away to Chelsea in the Carabao Cup, in which Ospina was also between the sticks, was in jeopardy.

It wasn’t.

Okay, Tom Pettersson’s penalty wasn’t the best but Ospina still actually had to throw himself to the ground without hurting himself – something he doesn’t usually manage.

And I doubt Pettersson was that gutted.

Arsenal haven’t kept a clean sheet in the Premier League with Cech as goalkeeper since December 16 against Newcastle.

With this in mind, it’s not really surprising that Arsenal fans are calling for the Colombian to take over as the team’s no.1. Although Ospina used to be the club’s comedy-‘keeper, Cech seems pretty keen to take up that role instead.

During his career, the 35-year-old has saved 16 penalties and none of them have been for Arsenal. This season, he’s kept just 10 clean sheets in 29 appearances – that’s a clean sheet for 34.5% of the matches he’s played in.

Ospina has kept six clean sheets in 11 appearances – 54.5%.

Admittedly, the 29-year-old has had fewer opportunities to mess up but, after watching a well below-par Cech in action this season, fans are genuinely considering whether giving Dave a chance as no.1 is such a bad idea.

It’s oddly unsettling.

Here’s what Twitter had to say over the penalty save:
