Deschamps, 41, insists that it will be a tough job to return home from Stamford Bridge with any reward because of Chelsea's strength in depth.
"Returning to Stamford Bridge will give me great pleasure," said Deschamps. "Although the stadium itself is renovated and much bigger, the wonderful ambience which I experienced remains.
"Chelsea have a very competitive European team with something like 20 internationals - a great compensation if you have injured or suspended players.
"Not only do Chelsea want to win this trophy, they are among four or five teams which can legitimately expect to do so. They won the Premier League title last season and are already performing really well.
