Leandro Rodriguez will be in the Everton squad to face Reading on Tuesday.
The 22-year-old Uruguayan could make his senior Blues debut at Reading in the Capital One Cup, Roberto Martinez has confirmed.
Rodriguez arrived from River Plate Montevideo in the summer transfer window and has scored in both his Under-21 outings for the Toffees to date.
Leon Osman and Darron Gibson could also be involved, Seamus Cleman is being monitored but Bryan Oviedo is a major doubt.
Martinez said at his pre-match press conference: “He is ahead of his development. I expected Leandro to take five to six months to be ready for the British game.
“I have been very impressed, not just in training but with the Under-21s as well. He has scored in both games and showed an incredible street footballer’s way of playing the game, which has helped him.
“He will be involved in the squad. Then it will just be down to the needs of the game and how everything goes if we see Leandro or not."
Martinez also hinted that Darron Gibson and Leon Osman could get their first senior match action of the campaign after returning to fitness.
However, he explained that he will leave it until the last possible moment before deciding whether Seamus Coleman, Muhamed Besic and Bryan Oviedo are able to make their comebacks from injury.
He continued: “Darron Gibson and Leon Osman have been stepping up their fitness programmes and that is very positive news. It was a bit of a disappointing start to their season with niggles and injuries so I am excited they are joining the squad.
“Bryan Oviedo, we don’t think he is ready to play a game yet but we will make a late decision on him.
“There is a chance Seamus could be fit but we are not going to know until late today [Monday]. It’s important that Seamus can train with the group before he is able to play.”
The manager also revealed that Mason Holgate picked up a knock in training but is still expected to be fit enough to be included in the squad that heads to the Madejski Stadium.
