That is the view of former Arsenal defender and BT Sport pundit Martin Keown.
Conte’s Chelsea side have already lost three Premier League games this season, leaving their title defence in doubt.
Yesterday they were beaten by bottom-of-the-table Crystal Palace at Selhurst Park to put them nine points off Manchester City at the top.
Keown has questioned Conte’s team selection following injuries to star duo Alvaro Morata and N’Golo Kante.
These subtle little changes when the first team players aren’t available, he’s not getting it right
And he also does not understand why Antonio Conte allowed Nemanja Matic to leave to join Manchester United in the summer.
“Pedro sat on the bench,” Keown said following the Crystal Palace defeat.
“You look at Conte last year and he couldn’t get anything wrong.
“Now these subtle little changes when the first team players aren’t available, he’s not getting it right.
Antonio Conte insists he's happy at Chelsea amid exit rumours
“They’re so excellent City now, and we talk about being ruthless on a football pitch.
“Why did Chelsea let Matic go? (Diego) Costa, of course, they fell out.
“But they’re weaker this year than they were, very obviously.”
Chelsea's next fixture is against Roma in the Champions League on Wednesday at Stamford Bridge (7.45pm).
