Four goals in his last five internationals and six for Aston Villa this season means Saturday's friendly against world champions Spain will mark the end of a defining week for Bent.
He said: "It's a massive week for me. I'm up there with the best periods in my career just as we're playing Spain, the best team on the planet.
"I kind of knew this was going to be a big season for me. The year before big competitions it seems to have gone well for me but then it hasn't paid off. Hopefully it'll be different this time.
"I've never been at the World Cup and we didn't qualify for Euro 2008 but this is a big chance to show everyone what I'm about and I'm looking forward to it.
"I've never scored at Wembley and would be delighted to break that duck.
"It's a big blow for England Wayne Rooney not being there because you need your World Class players at the big tournaments.
It's unfortunate he won't be there but if I'm selected I'll do everything I can to help."
