Stamford Bridge’s new recruit is relishing competition for places with his Spanish countryman.
Costa will arrive in London having had an excellent season with Spanish Champions Atletico Madrid, where he scored 36-times on route to their title success.
The Brazilian born Spaniard will join the likes of Demba Ba, Romelu Lukaku and Torres at the Bridge, as he looks to provide the solution to Jose Mourinho’s infamous striker problem’s from last season.
Costa admits he is looking forward to the battle with countryman Torres, and admits he will fight hard to win his place in the team.
"It's always good to have competition. The important thing for a big club is having great players," Costa told GloboEsporte.com.
"Torres is a great player, I know I will fight hard to be among the holders and I like it. So I think it will be a clean and healthy competition."
"I have wanted to play in the Premier League for a long time and I think it will be a very good and fast adaptation.”
Costa will begin his pre-season preparations with Chelsea in the coming weeks, following his relatively short World Cup campaign this summer, where Spain were knocked-out at the group stage round.
He joins the likes of Andriy Shevchenko and Torres himself as big-money strikers who have joined Chelsea in recent times. Costa will be hoping for better fortunes than those mentioned, as both seemed to fade under the pressure of a high-profile transfer.
A potential partnership with Lukaku would see Chelsea among the favourites to land the Premier League crown, with an attacking force containing pace, power, height, and most importantly a prolific ability in front of goal.
