Costa is Mourinho's Mr. Right
Jose Mourinho praised Chelsea for waiting for Mr. Right in Diego Costa after the Spain striker extended his blistering start to his Blues career with a hat-trick in the 4-2 defeat of Swansea.
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."
Costa cancelled out John Terry's own goal - just reward for Swansea's strong start as the Blues struggled to engage their press defence - before the interval and added two more to become the first Chelsea player since 1928 to score in his first four games.
Mourinho attempted to temper expectations regarding Costa, who he refused to compare with Didier Drogba, who netted five times in his first nine games for the Blues in 2004-05.
"I'm not looking for this (30 goals a season)," Mourinho said.
"If the team plays well he has to score goals. But the way he is playing and the team is playing if he keeps scoring a few goals, a few goals give points and points help the team to be in the top part of the table.
"Didier's start was 2004, 10 years ago, a completely different situation.
"Didier had a fantastic career at Chelsea and Diego is showing he can have the same profile of career. We don't need to compare careers and especially the players and especially the teams."
Mourinho spoke on Friday of his strikers being an upgrade on last term and the statistics prove it.
Fernando Torres, now at AC Milan on a two-year loan, netted five Premier League goals in 28 appearances last term.
Loic Remy, signed only after Torres' move to Italy, struck the fourth of the day, nine minutes after coming off the bench for his debut.
"It's a perfect debut," Mourinho said.
"No better start for the kid."
Drogba turned an ankle in training on Friday and is the only doubt for Wednesday's Champions League Group G opener with Schalke, which is followed by the trip to Premier League holders Manchester City.
Mourinho bemoaned the fixture list.
"We have fixtures that are like a poisoned gift for us," he added.
"Every time we play in the Champions League the next match we play is against Man City, against Arsenal, against Man United and against Liverpool. We have difficult weeks ahead of us."
Swansea boss Garry Monk was impressed with his side's showing and not at all disheartened by a first loss of the season which opened with three wins, including at Manchester United.
"We played some very good stuff first half," Monk said.
"We should've really come in with a lead, disappointed to have conceded that goal just before half-time.
"Second half you saw the power and quality Chelsea had and we couldn't quite contain them in the second half, which is disappointing."
It was a match which pitted the manager of the month, Monk, against the player of the month, Costa.
"And he won," Monk added.
"The whole (Chelsea) team is packed with world-class players that can cause damage to you at any time.
"We have to take that on the chin. We have to put it in perspective, but we'll always try to compete against whoever we play. It doesn't matter who they are. We did.
"Some of the football we've played was some of the best we've played against these type of teams."
