Semi-automated offside: Chelsea goal disallowed vs Dinamo Zagreb

Semi-automated offside was used as Chelsea lost to Dinamo Zagreb in the Champions League.

Thomas Tuchel’s side were shocked by their Croatian opponents with Mislav Orsic scoring the only goal of the game after 13 minutes.

Matteo Kovacic played a lovely ball over the top for Ben Chilwell to square for Aubameyang.

However, the striker’s celebrations were cut short after the assistant referee raised his flag.

That decision was confirmed by the new semi-automated offside that is being used in the Champions League this season.
