No, obviously not.
Or maybe you're clueless. VAR is hardly ever a process of just one passage of play, they're usually forced to check previous passages of play, just like the one with our goal. You've had a foul on Mata, Fred being offside and also I presume them checking whether Lukaku was absorbing the goalkeeper/defender's attention in the play and then it's the ref who decides whether he did or not. You've got three different decisions to make here, hence the time. Rewinding those passages takes time and getting used to, probably the ref who's doing the VAR review needs time to adapt to the technology it takes (remember the blunder with broadcasting which put some hilariously shit lines in our game earlier this season or the last season?).
