David Alaba seen grabbing the mouth of Austria's "bad boy" Marko Arnautovic during his wild goal celebration

Maverick Marko Arnautovic appeared to forget how to celebrate a goal after his wild behaviour in Austria's Euro 2020 opener.

Arnautovic looked far from happy after rounding the goalkeeper and slotting home cooly.

The 32-year-old who didn't start the game was seen ranting wildly during his celebration.

Austria captain and Real Madrid summer signing David Alaba took it upon himself to try and quieten down the hot-head.

Alaba grabbed Arnautovic's face to try and close his mouth during the unconventional celebration.
