Chelsea boss Jose Mourinho was delighted with hat-trick hero Diego Costa after their 4-2 victory over Swansea City.Chelsea continued their 100 per cent winning start to the Premier League season with an emphatic victory, with Costa taking his tally to seven goals from four games this term, a return Mourinho believes is abnormal.
"Seven goals in four matches surprises me, because it's something that is not normal," Mourinho said.
"Seven goals in four Premier League matches maybe is too much. We cannot expect that after eight matches he has 14 goals. It's to ask too much. Maybe the next four matches he scores two goals.
"But he's comfortable in the team. The team was built in a way where we were waiting for a certain type of striker.
"I think now everybody knows Chelsea did the right thing waiting for him. Chelsea did well by waiting and waiting for the right one."
