"We don't have that many great memories from our other visits to the Emirates. They played very well and we weren't in our best moment," said the goalkeeper.
"This time I think it is different because we are top of the table and I think it is easier to play when you are up there. We've never won there before, so maybe it's the right time to do it.
"It is possible for us to win on any ground. But we have to respect them a lot and play to win, like we always do.
"We have already won at Stamford Bridge, which we'd not done, so we're confident we can now go to the Emirates and win there too."
