But you missed out a very crucial point with regards to the advantage part and also interpreted the deliberate attempt one.
You think Lovren "deliberately" flicked the ball to Kane or was it a miscue attempt at clearance for a through ball which was played towards Kane. It's not like Dier who was not affected by Salah. Lovren was affected by Kane as he was automatically going to become active/dangerous if Lovren didn't attempt the clearance.
As for the advantage part:
- gaining an advantage by playing the ball or interfering with an opponent when it has:
- rebounded or been deflected off the goalpost, crossbar or an opponent
- been deliberately saved by any opponent
A ‘save’ is when a player stops, or attempts to stop, a ball which is going into or very close to the goal with any part of the body except the hands/arms (unless the goalkeeper within the penalty area).
This shows that Lovren was trying to save the ball going to Kane with a clearance which was not executed properly. Kane then got "advantage" from that botched "save" which did not include Lovren using his hands and the ball was moving towards goal.
The above lines show IMO that Kane should have been flagged offside.
