The England international knows showing what he is capable of against the reigning world and European champions can only enhance his chances of being on the plane to Poland and Ukraine next June.
Bent said: "I remember playing against Brazil a couple of years ago and thinking 'wow, I've never played a team like it'. This is going up another gear. Spain are the best team in the world, who won the last World Cup and the Euros.
"They've got players out of this world and will be a great game to be involved in.
"It would be great to play against someone like Spain and prove you can handle yourself at that level.
"There is no-one better. They are the top, top level and you are going to meet people like them next summer so it's a chance to show what you can do."
