The story of the match was nearly encapsulated in the first few minutes of play when Marcos Alonso's reckless challenge was punished with a yellow and Ben Mee headed straight at Thibault Courtois from the ensuing free kick.
"We kept going, kept probing and it's 3-0 at the interval".

Antonio Conte might not be happy with the lack of discipline shown by his senior players, but the spirit and fight shown by his side should be a positive sign, although Chelsea must avoid these self-inflicted wounds in the future.
Marcos Alonso's long-range drive was tipped over by Tom Heaton as Chelsea registered their first shot on target early in the second half, while Morata came on to replace the ineffective Michy Batshuayi in attack.
Vokes, who scored two of those goals in the first half, admits his side were sloppy to allow Chelsea back into the game but feels after an atrocious away record past year, it was a huge result for the team and the club.
Conte, looking exhausted and disgruntled, said he preferred not to talk about the referee who also sent off Cesc Fabregas in the 82nd minute after the Spaniard earned a second yellow card for an ill-timed tackle on former Chelsea man Jack Cork. "I think that the coach can make mistakes, the players can make mistakes, the referee [too]".
The Clarets made their numerical advantage count 10 minutes later as Vokes fired in his first of the afternoon from a Matt Lowton delivery.
'We didn't lose the balance'.
The Blues never quite recovered from that incident in the second half.
"Instead we conceded three goals and the second half was very hard to change the result, despite the great commitment, the great desire, the great will of my players".
"A lot was made of our away form last season", Vokes said.
The first XI has hardly changed from the side which romped to the title last season and while Burnley performed well, Chelsea really should be expecting to beat teams of their calibre.
