MARTIN ODEGAARD’S secret SOCK code for Arsenal’s sensational set-piece success could have been cracked – by Match of the Day.

Pundit Ashley Williams reckon he’s worked out why the Gunners are so “trigger” happy, especially in Saturday’s 5-0 win over Crystal Palace.

Martin Odegaard appears to indicate where he wants corners delivered

Odegaard could have been busted over a ‘signal’ at corners

The former Everton defender spotted midfielder Odegaard appearing to signal to Arsenal’s corner-taker – via his SOCKS.

Gabriel Magalhaes headed the Gunners in front from one such delivery.

Then, after another corner, Palace keeper Dean Henderson scored an own goal, and the same center-back assisted.

Arsenal only had six corners over the entire game, so that’s an impressive ratio.

And it confirmed the Gunners as the Premier League’s top scorers from set-pieces this season.

Ex-Wales star Williams said on the BBC’s MOTD: “There’s always a trigger for what the movement’s going to be.

“We can see they have worked on whether it’s a front-post corner or a back-post corner.

“If you keep an eye on Odegaard, we feel – maybe we’ve had too much time on our hands – but we feel that maybe he’s signalling something to the corner taker.”

The former Swansea hero, 39, suggested the Norwegian playmaker sends something like a footnote to his team-mates during games.

Williams explained: “He’s in the same place for every corner and he’s playing with his socks.

“There is synchronicity regarded whether they go to the front or the back. Every clip we see here he is doing the same thing where he’s playing with his socks. It might be coincidence, yes.

“But it is a big coincidence that he’s always there and always doing something with his sock.”

Still, there’s one aspect of Williams’ analysis that is predictable.

He thinks Nicolas Jover, the set-piece coach at Arsenal, is the brains behind their seeming scheme.
