Former Chelsea striker Tony Cascarino claims the Blues still need to sign another 'world-class' forward to help Fernando Torres and Demba Ba.

The former Newcastle man has made the move to south west London after a year-and-a-half with the Magpies, where he became one of the hottest properties in the Premier League.

But Cascarino believes Rafa Benitez's side are still short in the striker department and should be targetting a 'world-class' signing, like Radamel Falcao, to help push the club up the table.
