"I hope he gets in," Oviedo is quoted as saying by the Daily Mirror. "He is working for that and we saw in the last game against Manchester City, he had a fantastic game.
"It would be good for him to go to the World Cup for the experience and because he is a very good player.
"To have a player like him is very good for England because sometimes you need a player who can come on and win games. I think Ross is a player like that.
"Maybe he can sit on the bench and then come on and score a goal to win the game. He can make a difference."
As for Oviedo, he is facing a race against time to be fit for the showpiece event after suffering a double fracture of his leg in Everton's FA Cup clash against Stevenage in January.
While the 24-year-old utility is back training, he will not risk his future by returning to the field ahead of schedule.
"I have to be honest with myself," Oviedo said. "Of course I want be in the World Cup. It’s one of the best experiences a footballer can have but I need to be honest for my career.
"I want to be ready for the World Cup but I don't want to go to and then come back to Everton and when I start to play have a lot of injuries. It's not worth it for me."
