The former Tottenham player is aiming to prove the England head coach that he what it takes to be an England regular by scoring plenty of goals for Sunderland in the Premier League this season, which ends with the World Cup finals in South Africa.
"It's still a massive ambition, but at the same time I know its going to be difficult to get back in," Bent said.

The Debate: Does Michael Owen deserve an England recall?
"He (Capello) seems to have his four or five strikers set, but if I can score a lot of goals, that should help me upset the system a bit. If that's the case, there's no saying where I can go."
Bent, 25, has scored two goals this season following his his club-record £10 million switch to Sunderland from White Hart Lane and will aim to prove his point to Capello this Saturday when Hull head to the Stadium of Light.
"Im always confident that I can a score a lot of goals," Bent added. "I've started off this season with a couple already, and if I can score a few more, that can only help my international ambitions.
"My number one goal is to hold down a place in the Sunderland team and do well for them. If I do that, the England honours will come.
"I definitely feel that I have something to add - the moment I stop thinking that, I might as well stop playing football because the ambition will be gone. Hopefully, it will come with time.
"It's similar to when I was at Charlton - whenever the England manager came down there it was a big occasion for the English players in the team.
"When we played against Chelsea the other day, the manager (Steve Bruce) whispered in my ear in the dressing room, 'You know the England managers here?' He had a cheeky grin on his face.
"It was nice to see him hear, and if I keep playing well for Sunderland, hopefully he'll want to come back again soon."
