Chelsea boss Jose Mourinho was clearly unhappy with his side's third place finish last season, and set about retooling his squad last season. Filipe Luis and Cesc Fabregas came in to replace Ashley Cole and Frank Lampard respectively, whilst it was no surprise to see Mourinho overhaul his attacking options.
Demba Ba, Samuel Eto'o and Fernando Torres all struggled to find the back of the net on a regular basis last season, and all three have moved on - along with Romelu Lukaku, who was sent out to Everton on loan last season before completing a £28m permanent deal.
Around £40m was spent by Mourinho on attacking reinforcements, as Diego Costa, Didier Drogba and Loic Remy all arrived from Atletico Madrid, Galatasaray and QPR respectively. So far, Spanish international Costa has lived up to his £32m price tag having hit four goals in three games - and ex-Blues winger Boudewijn Zenden believes that Costa can have a similar impact to Drogba's first spell at Stamford Bridge.
"We all knew Chelsea lacked strike power up front," he told TalkSport. "With Diego Costa coming in, he’s the type of player who can do what Drogba did during his first period at Chelsea."
Ivorian international Drogba arrived at Chelsea with a similar reputation to Costa back in 2004. Having hit 32 goals in his first two seasons in West London, Drogba became a cult hero with Chelsea fans off the back of his growth as one of the top strikers in Europe.
The early signs look good for Costa, and if he can score as many goals as Drogba, then Zenden's prediction will become reality - and Chelsea will become title favourites as a result.
