The German club will take on Real Madrid in the semi-finals of the competition, the first leg of which will be held at the Signal-Iduna Park on Wednesday.
"If you're talking about the Champions League, of course it's our dream – not just mine but that of all children born with the desire to play football," he told UEFA.com. "To play in the Champions League and to reach the final. And then talking about Wembley, a special stadium – it would be marvellous.
"And personally speaking, I think that in terms of how I feel as a player, I'm at 100% which is good for Borussia Dortmund. Borussia Dortmund benefit because they have three [centre-halves] at the same level. And at any moment any of us can play and play well.
"We are facing Real Madrid and we already know each other. There is mutual respect – and we know about the difficulties. So we will put into practice everything we have shown so far in the Champions League, so we can leave [the second leg] with a victory and continue our dream."
Dortmund won the Champions League in 1997.
