Gary Neville had warned Arsenal that they were "done" if they lost Gabriel Jesus for a prolonged period as fears grow around his injury.
The Brazil forward will miss the remainder of the World Cup after picking up a knee issue in their final group game against Cameroon. It was Jesus' first start of the tournament, but he came off with just over an hour played. A scan has now highlighted the problem, which will leave Arsenal sweating on the full diagnosis.
Originally it appeared as if Jesus could miss just a month, but reports claim the Brazilian could now be absent for up to three months. That would threaten to derail their Premier League campaign with the forward crucial to their early season form that has them sat top.
