Chelsea's attempt to defend its Premier League title faltered once again overnight as a 1-0 defeat at West Ham saw the Blues register a fourth loss of the season.
Chelsea wasted an opportunity to close an 11-point deficit to leader Manchester City, which faces second-place Manchester United on Sunday.
"To talk about a title race after a defeat I think is a bit strange," Conte said. "Especially if this is the fourth defeat in this season in 16 games. When you have this start it's impossible to think you are in the title race."
Marko Arnautovic's early strike was backed up by a resilient defensive display that ended an eight-game winless run for the hosts and provided a first victory under David Moyes.
