A new technology made its debut in the Premier League during Manchester City's clash with Crystal Palace on Saturday.
The visitors got off to a flying start in the weekend's early kick off, with Palace taking a two-goal lead after just 21 minutes courtesy of strikes from Eberechi Eze and Chris Richards.
Oliver Glasner's side were well in control throughout the early going and looked to have extended their lead even further when Eze managed to get in behind the City defence.
The England international subsequently slotted past Ederson to seemingly make it three but soon found that his goal would not stand after all.
