Chelsea have every chance of winning the Premier League title this season, former Blues goalkeeper Mark Bosnich.
Frank Lampard's side are just two points adrift of table leaders Liverpool and Tottenham, having gone unbeaten in their last 13 games.
"I think they are genuine contenders," former Blues goalkeeper Bosnich told Sky Sports.
"I think the addition of Mendy in goal, Thiago Silva at the back and some of the other players, players like Timo Werner, Kai Havertz and Christian Pulisic, they are slowly but surely getting to grips with the intensity of the Premier League.
"I thought it at the start of the season and nothing has changed my mind that they are genuine contenders.
"It's going to be very difficult for them, and I think Frank and his staff will know that, but they are in very good hands with someone who has won things before and someone who knows exactly what it takes to win."
