Arsenal striker Eddie Nketiah says he has been in contact with Gabriel Jesus after he sustained a serious knee injury.

The 25-year-old underwent surgery earlier this week after sustaining medial ligament damage during Brazil's 1-0 World Cup defeat to Cameroon. Reports have suggested that this could rule him out for as much as three months, presenting a potentially devastating blow to Arsenal's title hopes.

"I spoke to him and wished him a speedy recovery," Nketiah said. "It is never nice to see anyone miss a World Cup and also for us as a team he is a big player, we are going to miss him. We are all behind him."

On their friendly win against Lyon, Nketiah added: "The mentality has been top from the beginning. The manager has instilled that in us and all the boys have belief and work hard every day. It is good to be in a great position, we're hungry to do well.

"Each win brings more confidence. If we keep going and working hard the way we have over the first half of the season it will do us well for the second half of the season."
