Bent is keen to impress with Villa this season in hope of winning back his place in the England squad after he failed to recover in time from an ankle ligament injury to be chosen by new head coach Roy Hodgson for Euro 2012.
He said: "It was hard to watch but I was supporting everyone again. I wanted them to do well in the tournament and it's unfortunate they went out on penalties again but I was watching as a fan and hoping we were going to win.
"All I can do now is concentrate on my club form. That's all I can do really.
"If I score goals for Villa and we play well and win games it's only going to help me get back into that England squad."
