Chelsea manager Jose Mourinho says he's delighted with how his players are scoring goals.
The Blues were impressive on Saturday as they easily disposed of Aston Villa 3-0 to stay top of the Premier League but Mourinho insists there's still room for improvement.
"We are playing well, we have different players scoring goals," Mourinho said after the game.
"We are scoring goals in different ways; the only way we haven't scored is from a penalty, because we haven't had a penalty.
"We are not perfect; we have a lot to improve, in every area of our game, but we are doing well."
Spain's Diego Costa scored his eighth goal in six Premier League games but the Portuguese says he only cares about getting the goals and winning matches.
"I don't care about Diego's goals," added Mourinho.
"I just care about the team scoring enough goals to win.
"I know for a striker scoring goals is always nice for his confidence, especially for a player like him, who is not training as he should because we are protecting him in certain situations.
"[He recovers from matches by] doing almost nothing, just resting and recovering from the tight muscle he has every time he accumulates fatigue.
"If he doesn't go to the national team and stays here for 15 days, just in treatment, recovering and making the muscle stronger, he has the perfect chance to be in top condition for Chelsea and the national team."
