KAI HAVERTZ revealed he was shocked at what Casemiro was doing in the build-up to Arsenal's winner at Manchester United.
Quick thinking from the German set-up the goalscoring chance, with Havertz's low cross tapped in by Leandro Trossard.
That ended up being the only goal of the game as Arsenal ensured the title will be decided on the final day of the season.
But it only came about thanks to some ponderous defending from Casemiro - and Havertz's ingenuity.
The Arsenal star revealed he noticed Casemiro out of position and playing him onside, so quickly made sure the ball was played forward to him quickly.

Havertz told Sky Sports post-match: "I looked to my right and saw him still on the 6-yard line and I called Ben [White] and he saw me straight away.
"Then it was a one vs one situation and this guy [Leandro Trossard] scored."
Arsenal's win means they still have a chance of winning the title - but need rivals Manchester City to drop points.
Pep Guardiola's side face a trip to Tottenham on Tuesday and Havertz revealed he will be cheering on the Gunners' North London rivals.
He said: "I'm gonna be the biggest Tottenham fan ever on Tuesday."
