In contrast, the West Londoners need three points to keep the pressure on Liverpool at the summit, but the Portuguese believes that the Swans represent a banana skin of sorts.
"They are a good team, they play good football. Especially at Swansea it is never easy and Chelsea knows that better than other teams," he told reporters.
"They still need the three points, they are not in big danger like other teams but they still need a couple of points to stay in the Premier League and of course they will try to get points out of this game."
Tomorrow's clash in South Wales is scheduled to kick off at 4.07pm.
