WEARING THIN BLUE LINE

LIAM ROSENIOR has warned his Chelsea players they must remain disciplined as they take on "world-class" Paris Saint-Germain tonight.

Chelsea go to Parc des Princes for the first leg of the last-16 clash less than eight months after beating the Champions League winners to become world champions.

The French champions have come in for a lot of criticism following their 3-1 defeat to Monaco last Friday but they are still top of the Ligue 1 table.

And Rosenior who is returning to France just over two months after leaving Strasbourg - has urged his side to forget the negative talk surrounding their opponents.

He said: "PSG were so good last year. Obviously I was here in this country witnessing them go through their journey to win the Champions League and I was admiring it.
