The midfielder has enjoyed a fine campaign for Roberto Martinez's side.
The Blues youngster has been in impressive form this season, bouncing back strongly from a disappointing year last season.
So far he has eight goals and seven assists to his name in the Premier League, with a number of eye-catching displays looking likely to earn him a place in England’s squad for Euro 2016.
There is fierce debate about his best position though, with people offering various ideas on the debate. Moyes though, simply believes his best role is playing up by the front end.
“Roberto has done a great job on developing him and bringing him on,” he told Goals on Sunday.
“I think Ross himself is maturing too. He was a boy and I think sometimes we build up boys too quickly when they’re too young and expect too much of them.”
“Ross just needed time to develop and get games under his belt and find what his best role is. At the moment I think his best role is playing up by the front end, making passes and he’s got the ability to take people on.”
Aside from Roberto Martinez, England manager Roy Hodgson will also be hoping that Barkley can maintain his form this season.
It is shaping up to be an exciting summer for the national team, with the likes of Barkley, Dele Alli and Harry Kane all enjoying fine campaigns and looking set to be big stars for their country in Euro 2016.
If they can maintain those type of performance in France, England stand a strong chance of being big contenders in this year’s tournament.
