The defender has called on his teammates to no longer think about this weekend's home loss against Real Madrid, and turn their attention to the match versus the Blues instead.
The Blaugrana were beaten 1-0 in the first leg of their semifinal tie against the Premier League side, and Puyol has made it clear that they are determined to turn things around in the return.
"We now have to focus on Tuesday. It’s a competition we are keen to win and we are close to another final," Puyol was quoted as saying on the Barcelona website.
"We have to be very aware of their counterattacks. I can see it being a similar game tactically to the Madrid match," added Puyol, who also said it'd be an "attractive final" should Barca meet Madrid.
