Riyad Mahrez's second goal for Manchester City against United in the Premier League derby caused controversy on social media in many ways.
The Cityzens were 3-1 up until injury time but the Algerian raced through and finished past David de Gea but celebrations were initially cut short due to the raising of the offside flag.
In a very tight decision that reminisced what happened to Romelu Lukaku at Wembley, after much deliberation, Michael Oliver was told to overturn the on-field decision to the joy of the City fans inside the Etihad Stadium who will be grateful for Alex Telles' noticeable green boot that led to this change of heart.
