Arsenal have been handed a title boost with striker Gabriel Jesus now training on grass and "pushing the boundaries" ahead of a highly anticipated return to action.
Jesus, 25, has been sidelined since the World Cup after hurting his knee while playing for Brazil.
Gunners manager Mikel Arteta said on Jesus: "He's doing more and more on the field. The knee is not reacting, really positive.
"He's pushing the boundaries right now."
The Spaniard added: "We want him back as quick as possible, but also respecting the timescale that the doctors and the specialists are giving us."
