The midfielder has been a star man for Everton again this season.
The youngster has been in impressive form this season, after a disappointing campaign last year saw him struggle following an injury at the beginning of the campaign.
He already has seven assists and eight goals to his name in the Premier League so far this season, with that kind of form making him a certainty to head to Euro 2016 with England.
And Roberto Martinez says he has now fulfilled his potential, insisting that his form shows he is no longer the young man that broke onto the scene two years ago.
“If you see Ross playing week in, week out, you realise he has gone from a young man with incredible potential, into a reality,” he told Talksport.
“The way he is playing at the moment, you can see he is a special footballer and he will get better, but he’s not a young man anymore.”
“He’s playing well beyond his years, he’s taking responsibility and he’s very much trying to improve in every way.”
The Blues will certainly be hoping that Barkley can continue this kind of form for the rest of the season as they hunt down a potential place in Europe.
His displays do leave England boss Roy Hodgson with a big question to answer though, with him having to choose between Barkley and Tottenham Hotspur starlet Dele Alli for his first team in the summer.
It is unlikely he would choose both as starters, although that is certainly something English fans would love to see given how both have impressed during this campaign.
