Barkley signed a new four year deal at Everton in the summer but the speculation over his future won’t go away with neighbours Liverpool and Manchester United reported to be interested, too.
But Goodison boss Martinez is totally chilled about keeping midfield sensation Barkley and other young talent like defender John Stones.
There are no buy-out clauses in their contracts and Everton are financially sound enough not to have to flog their star players to pay the bills.
Martinez said: “I don’t think it is easy to get footballers like John Stones and Ross Barkley. I think as English players they are phenomenal footballers and you are going to get that.
“As a football club we want John and Ross to keep progressing, keep developing and they know they can do that with Everton. And that’s the only thing that matters to me.
“I’m not going to just be worried about other teams’ interest because there will be interest, there’s no two ways about it. These two players are as good as it gets in terms of that age group, if not European football.
“It’s a matter of making sure they keep progressing and keep developing. If I see they keep developing with us there is no need to worry.
“We are a club which does not have to sell. We have gone past that period and the football club is in a fantastic moment financially. Everything will be football decisions.
