"I would prefer for us not to face any Spanish team. I don't want Madrid because it would be too emotional to return to the Santiago Bernabeu wearing another shirt," said the 33-year-old, who won the Champions League three times with the Spanish giants but was also part of the Madrid side that has failed to get beyond the last 16 in six successive campaigns.
He added: "For me it's a special competition. I've gone many years without getting past the last 16 and to be in the quarters will be special. We are performing at a great level in the cup competitions and where we haven't been consistent is in the Bundesliga.
"Hopefully we can achieve two or three wins so as not to suffer towards the end of the season."
