Fabio Capello maintains that anyone struggling for games at club level will not be going to the World Cup.
The England boss is finalising his plans for this summer's showpiece in South Africa and will have a good idea as to the make-up of the squad he would like to take with him.
There are, however, a few places still up for grabs, with a number of players pushing hard for a place in the final 23-man travelling party.
Manchester United striker Michael Owen is among those regularly mentioned as a World Cup possibility, with the experienced frontman chasing down Sir Bobby Charlton's all-time scoring record.
He has been unable to hold down a starting berth at Old Trafford this season, though, and Capello insists he will not break his selection philosophy for a player short on big-match practice.
"Am I under pressure to call upon certain players?" Capello said in an interview with Gazzetta dello Sport.
"A lot of people would like to see me select Owen. He is the best English goalscorer of his generation but if he doesn't play, I cannot pick him."
One man guaranteed to make the cut, providing he can steer clear of injury, is Owen's United team-mate Wayne Rooney.
The 24-year-old has been in blistering form this season and Capello admits he can now rightly be regarded as one of the finest talents in world football.
"Rooney compared to (Lionel) Messi?" he said.
"They are two players that everyone would like to have, along with Cristiano Ronaldo.
"Wayne is an extraordinary player, talented and willing to learn. (Sir Alex) Ferguson has taught him so much.
"I have told him that he must make sure he plays inside the box and he must continue to score goals.
"The departure of Ronaldo at Manchester United has empowered him and is now integral to their plans."
