So, after an opening day 3-2 defeat to lowly Burnley with nine men, there should be enough warnings from history for Antonio Conte to feel slightly uneasy about his position at Stamford Bridge as the Premier League champions prepare to visit Wembley this weekend for what has become a crucial clash against last season's runners-up, Tottenham.
Hazard, who had ankle surgery earlier this summer, is not yet being considered for a first-team return.
"I dont think its a good time to play them", Conte groaned. "We must be focused on the pitch on the game and to try and do our best and not find an excuse", Conte told a press conference.
"About Bakayoko, he is improving very well he is not at the top of physical condition". He is not at the top of his physical condition but I think he could be in contention because in this moment I don't have other midfielders available. This situation is not easy at the moment.
"At this moment some players don't have 100 per cent".
Pedro Rodriguez is also an injury doubt for Chelsea after missing the Burnley game with an ankle knock, but despite sitting out training earlier this week hopes are high that the Spain global will be fit to face Tottenham.
Chelsea sold Nemanja Matic to Manchester United last month - and are pushing hard to sign Leicester star Danny Drinkwater - and Conte admits he's lacking options in midfield in the lead-up to the London derby.
"Also Morata is another player to continue to work to".
"Pedro has today has trained with us, he felt pain in his ankle".
"I don't know if he is available on the bench. It could force me to take a hard decision, because in this moment some players are not 100 per cent in their physical condition", he said.
