A dip in form this season has not helped his cause and Wright fears his son's desperation to help Manchester City finish in the top four and cement a place in Fabio Capello's squad is actually harming his chances of going to South Africa this summer.
He told talkSPORT: "He's playing when he's injured and I'm trying to make him realise how important it is this year. If he misses out on this World Cup, then it might not happen again.
"But he says, 'Dad, what do you want me to do? If they want me to play, I've got to play'. I say, 'You're going to play when you're half injured? You're not doing anyone any good'. He's played and then they've left him out.
"He's lost form and so I'm thinking to myself that he's not going to make the England team, not even make the bench. Then for him to come on and do what he did and be really positive like we've told him to be, I felt like I was going to cry last night.
"It's been a really hard couple of months with Shaun with what's going on at City. I'd love him to be settled so he could just concentrate on getting them into the top four. That's what he wants to do and then, God willing, he can end up getting on the plane and going to the World Cup, doing well for England and everything would be great.
"That's what I would like to happen. But you know how football is. It's different from one week to the next."
