Chelsea boss Jose Mourinho is excited by Diego Costa's form going into the new season. The Spain striker struck twice in victory over Real Sociedad this week.
Prior to the game he apologised to the Chelsea fans for helping to knock them out of the Champions League while at Atletico Madrid last season but Mourinho is confident he'll he a firm fans' favourite.
Mourinho said: "Diego is a team player who works hard, he's not just about goals.
"It's about his defensive work, mentality and ambition. This is the player we bought and we were waiting for since last season.
"This is why we didn't buy a striker in the winter market. We were waiting for him, we have him and hopefully everything goes well.
"He looks adapted to the team, and the Premier League, not just Chelsea, should be happy. Sometimes we lose important players going to other countries and sometimes we bring new top players here.
"You can consider that [a bargain] because the market is crazy and the values are very high. For a striker like him, a champion in Spain, a Champions League finalist, a 25-year-old, we consider the price was very much in our favour."
