Reigning English Premier League champions kicked started their title defense on the wrong foot, as the Blues twice threw away a lead to draw 2-2 with Swansea in their 2015-16 season opening game.
In the second half of the Stamford Bridge tie, with Jose Mourinho’s men leading 2-1, goalkeeper Thibaut Courtois received a straight red after bringing down Bafetimbi Gomis in the penalty box, resulting in a spot kick which saw the Swans rescue a point.
However, despite this, after the game, the Special One had no criticism for his Belgian shot-stopper. Instead, his anger was directed towards his medical staff for an incident that occurred with only six minutes on the clock.
With ten-men Chelsea already struggling to cope with Garry Monk’s crew, the medical team decided on treating midfielder Eden Hazard after being tripped by Gylfi Sigurdsson, though the Belgian appeared not to be hurt, meaning he had to be taken off the pitch, leaving Chelsea with only nine men.
"I was unhappy with my medical staff. They were impulsive and naive," said Mourinho.
"Whether you are a kit man, doctor or secretary on the bench you have to understand the game.
"You have to know you have one player less and to assist a player you must be sure he has a serious problem. I was sure Eden did not have a serious problem. He had a knock. He was tired."
The Portuguese boss, however, refused to discuss about the referee’s decision to send off Courtois, saying: "I don't want to talk about it."
Jose also stated that his side were playing “very well in the first half”, but felt pushing for a win with one player less was an uphill struggle difficult to overcome.
"If you have 10 men and are winning you can defend well and try to find a strategy but to play with 10 men and try to win the game is more difficult. I would say we were the best team with 11 players and with 10 we fought hard, some fighting at the limit of their condition."
