Antonio Conte has admitted that Chelsea's clean injury record has boosted their chances of becoming champions as they aim to seal the title against West Brom.
The Blues currently have no players injured and have had no long-term absentees all season, taking advantage of their lack of European commitments to select a consistent side with only limited rotation enforced.
Conte is hoping to seal a domestic double by beating Arsenal in the FA Cup final after Chelsea have sewn the league championship up and credited Chelsea's behind-the-scenes staff for the part they have played in keeping his key players fit.
“I think this season we are very good, and also we are also a bit lucky to have the possibility to avoid a lot of injuries," Conte said at a news conference at Stamford Bridge. "We didn't have a lot of injuries this season.
"When you have this type of situation, without a lot of injuries, usually you try to play not with the same players. To use 15 or 16 or 17 players. I think this season we worked very hard, but we are also very good and we are also very lucky.
"I think that all this season we worked very hard on the physical aspect, and the tactical aspect, to try to avoid this type of situation. To avoid having a lot of injuries.
"Our work is a bit of a secret because we don't have a lot of injuries. For this reason, I have to say thanks to my staff."
