5) A Drogba replacement is needed
With Didier Drogba leaving Chelsea at the end of his contract, that does leave a gap in the squad that needs filling. Costa and Loic Remy both spent a lot of time out injured last season and will need backup. Of course, Falcao could be more than just a reserve if he reaches his best form, but that would undoubtedly be a great option for Mourinho’s side.
