Diego Costa would have considered himself a lucky boy on Monday night.
Launching himself in a late tackle on West Ham goalkeeper Adrian always carried an element of risk. Even more so when you consider he was already on a yellow card.
Indeed the Brazilian-born forward went flying in on Adrian, missed the ball entirely and caught the keeper very high on his standing leg.
Referee Anthony Taylor surprisingly gave the benefit of the doubt to Costa, only for the striker to go on and score a last minute winner to hand Antonio Conte a victory in his first Premier League game as Chelsea manager.
However, it could have been an entirely different story had Taylor seen a different angle of Costa's earlier challenge, which would have almost certainly seen him being sent off.
The victim of the tackle was criticised by Chelsea fans, who thought Adrian was overreacting to get Costa sent off.
But a day after the game, the Spanish keeper posted a still image of the challenge which showed just how fortunate he was to escape a serious injury.
Late on Tuesday night, Adrian published the photo on his Instagram account, accompanied with the caption: "Disappointed about last night!!
"Thank God my leg is okay after that, could have been much worse!! #fairplay"
West Ham will feel disappointed to walk away from the match without a point after fighting back so resolutely following Eden Hazard's early second half penalty.
Slaven Bilic will be forgiven for thinking James Collins' left-footed strike had earned his side a draw but Costa's late intervention meant all three points stayed at Stamford Bridge.
For Conte, however, he must keep a close eye on Costa. The 27-year-old has been absent all too frequently over the last few seasons due to suspension and he is already walking a tightrope after the opening game.
It will be equally frustrating for the club's supporters, though, as Costa struggles to have any sort of influence on proceedings if he isn't playing right on the limit.
The new Chelsea boss will have to find the balance to get the best out his star striker and keep him available for most of the season to get the Blues back in the hunt for Premier League glory.
