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