Chelsea boss Jose Mourinho believes Arsenal are favourites for Monday's big game.
Chelsea travel to Sunderland in the Capital One Cup quarter final tonight - and Mourinho feels the encounter leaves his side at a disadvantage going into next week's match.
"To play a game in the same week you play the second against the first is a strange week, especially because Arsenal do not having this game," said Mourinho.
"It's our fault. I can guess that they are having a couple of days off. I can guess they are going to prepare for the game calmly, tactically they be very well prepared.
"We have to travel, we have to play, we have to come back. But it's the quarter-final. When you are in the quarter-final, you smell the final. We are going to try."
