Manchester City forward Gabriel Jesus has vowed to return to pre-season training '100% fit' after fracturing his eye socket on international duty with Brazil.

The 20-year-old suffered the damage in the second half of the Selecao's 1-0 defeat to rivals Argentina in a high-profile friendly at the Melbourne Cricket Ground last Friday.

Nicolas Otamendi was the player who caught Jesus in an aerial challenge, but the former Palmeiras ace has attempted to absolve his clubmate of any blame for the coming together and is hopeful of returning to action on time.

"I still do not know [how long it will take]. I'll complete the tests," he told reporters. "I still don't know the gravity, but it's nothing too serious, nothing to worry about too much.

"If I have to have an operation, I will, and then I'll rest on vacation to return to Manchester 100%. It was a very normal move, it was unintentional. There was no malice on [Otamendi's] part. He's a good guy."

Jesus scored seven and set up four more in his 10 Premier League outings for Man City last season upon making the switch from Palmeiras.
