Ball was played backwards so can't be offside.
This happened in the Chelsea game as well, Maddison was flagged offside and then the incident was just never shown again, so impossible to say if he was actually offside or not. Very odd decision by the broadcasters to just disappear the incident.
Agree on the handball rule, IFAB have messed up biggly. The original way handball was done was that it had to be intentional, then the referees got guidelines so players couldn't just make themselves bigger using their arms and claim non intentional handball. Now it's a farce with different rules for defenders / attackers.
What I found interesting from game last night was James boot in foul. In La Liga this weekend Modric & Molina both made very similar challenge to that, it went to VAR, ref looked on the monitor, and they both got sent off straight red.
