Chelsea have a nasty habit of buying big-money strikers and turning them into flops. In May 2006, Andriy Shevchenko joined from AC Milan for £30 million and bombed in England, while Fernando Torres became the sixth most expensive footballer in history when he joined the club for £50 million in 2007, and look how well that's turned out. You can't help but fear for Diego Costa then, who has become the Blues' latest multi-million pound recruit, joining from Atletico Madrid for £32 million. It remains to be seen if the Brazil-born Spain international will live up to his price tag or follow in the footsteps of his infamous predecessors. If it doesn't work out for him in his debut season, at least Chelsea have back-up in Didier Drogba. Drogba knows what manager Jose Mourinho expects from his 'No.9's' having played that role so successfully under the 'Special One' before, and could fit right into his formations and apply his tactics. While it is hugely likely the Ivorian will be used primarily as an 'impact sub', he has the ability to turn a game on its head - In the Ivory Coast's opening match of this summer's World Cup against Japan, he appeared as a second half substitute with the team trailing 10. Within five minutes of his arrival, Les léphants scored twice to win the match 21. This ability could pay dividends if the likes of Costa or Torres are having a bag game, and the option of alternating his attack will afford Mourinho that extra bit of flexibility next season - and perhaps insurance against the Blues' track record for failed forwards. What do you think? Are Chelsea making the right decision in re-signing Didier Drogba? Let us know in the comment section, below.
