It turned out to be a decision that didn't prove too costly, but Leandro Trossard's disallowed goal against Leicester City has left some Arsenal supporters in a state of confusion.
The £21m January signing from Brighton & Hove Albion thought he had broken the deadlock in the 26th minute after picking out the top corner from just inside the box. However, following a VAR check and referee Craig Pawson reviewing the goal on the pitchside screen, it was decided that the goal wasn't allowed to stand.
As explained by the Premier League on Twitter, Ben White was the cause after committing a foul: "Leandro Trossard has the ball in the net for Arsenal, but after consulting VAR, referee Craig Pawson has overturned the goal because of sustained holding from Ben White on Danny Ward in the build-up."
