"Itâs a great acquisition for Chelsea,â Cascarino told talkSPORT. âYou only have to look at the relationship between Drogba and Frank Lampard in Jose Mourinhoâs most successful team. You see a forward who could hold the ball up and create things. That then helps the midfielder get goals. Chelsea havenât had a relationship like that since.
âDemba Ba does it OK but he doesn't do it to the level Jose Mourinho wants. Costa will give him that.â
