Jose Mourinho believes that Diego Costa is 'not normal', as the striker’s blistering introduction to English football showed no sign of abating with a hat-trick against Swansea. The 25-year-old was superb on Saturday as the Blues dealt with an early scare from Garry Monk's impressive side to hold on to their impeccable Premier League record. It means that Costa now has a remarkable seven goals in four league games since his £32million move from Atletico Madrid in the summer and further enhances the belief that Chelsea came out of the transfer window as clear victors.
