The Toffees boss has lavished praise on his 19-year-old playmaker, claiming that his level of ability is comparable to a player schooled in Holland or Brazil
Barkley has enjoyed something of a breakthrough campaign so far this term, having appeared in all 11 of his club’s Premier League fixtures as well as making his international debut in September.
The 19-year-old made his second appearance for Roy Hodgson’s side in Friday evening’s meeting with Chile at Wembley, and his club manager is convinced that the promising midfielder possesses the temperament to match his footballing ability.
"Ross, since day one, showed he was ready and in a position to enjoy his football and it is not a secret he is a really talented man," the Toffees boss told talkSPORT.
"Technically he is really gifted and you would probably see that technical ability in any player brought up in Brazil or Holland - he is that exquisite technically.
"He is a young man who is fighting for his place and his personality and character means he is such a humble boy, all he wants to do is listen and play.
"Nothing will faze him on a pitch and if you have that with the talent he has it is an incredible combination."
Martinez’s Everton side have enjoyed a fine start to their league campaign and will go into Saturday’s Merseyside derby sitting in sixth place, only three points behind neighbours Liverpool.
They have, though, failed to find the net in their previous two fixtures, although the ex-Wigan boss claims that the goals will begin to flow more freely for his new side as his players continue to get to grips with one another on the field.
"The goalscoring of ability of a team is very important. You are going to be successful in a season if you are solid defensively and have a threat of scoring goals,” added the Spaniard.
"Scoring goals will come more often once we get the understanding of the players.
"We have goals in the side, I'm not worried about that. The focus is on the strikers but it is the wrong focus.
"We are better now than we were in August and in February we have to be at a better level.”
