CHELSEA boss Antonio Conte has given up on his team's English Premier League title defence after a shock 1-0 defeat at West Ham.
Marko Arnautovic's early goal condemned the champions to a first defeat in eight league games to leave them 11 points adrift of leaders Manchjester City, who took on Manchester United overnight.
"We have to consider that this is the fourth game we've lost in 16 games,” Conte told Sky Sports at the London Stadium.
"In my previous experience, it won't be possible to fight for the title.”
The win did not move West Ham out of the relegation zone but they are now level on points with West Brom who lost to second from bottom Swansea 1-0.
Wilfried Bony's second goal in as many games gave the Welsh side its first win in seven matches to move off the bottom.

Tottenham, meanwhile, got back to winning ways in style, ending a run of four games without victory with a thumping 5-1 home win over Stoke City at Wembley.
It was Spurs' fourth successive four-goal win over Stoke, making Mauricio Pochettino's side the first team to have won by four goals in four consecutive English top-flight meetings with the same opponents.
Spurs moved above Arsenal into fifth place on goal difference ahead of their local rivals' trip to Southampton overnight.
