The two Toffees youngsters have been in outstanding form so far this season, and Barkley added another two goals to his tally, in his side’s 4-0 win over Aston Villa yesterday.
Martinez doesn’t feel that it is just the pair’s talent which makes them such outstanding prospects though, with the Spanish manager keen to point out their wonderful attitudes after the contest.
"I think we all agree that he [Barkley] is a special talent and a young career as you mention is quite exciting," Martinez said.
"What I love about Ross is just his passion for the game, it's very rare. In a new generation of footballers it is very rare to see a player like Ross Barkley or John Stones who are in love with playing the game.”
Barkley’s double for Everton took the headlines, as they stormed to success over Villa.
The attacking midfielder notched two close-range finishes against the Claret and Blues, and he kept up his brilliant run of scoring form this campaign.
Stones’ role in the fixture was a more unsung one, but the defender’s passing ability still caught the eye, as he set-up numerous Everton attacks.
The pair’s excellent start to the campaign has helped Everton climb into seventh place in the Premier League table, with Martinez’s side’s next match coming against relegation threatened Bournemouth at the weekend.
