No team in the top half of the Premier League has conceded more than Chelsea's nine goals so far and they have now let in nine in their last four in all competitions.
Conte switched from a back four to a back three in the second half in hope of an improvement but the damage was already done.
"I think I have to solve the situation," Conte said. "The situation is every game we have conceded two goals at a minimum. For this reason, two back, three back or four back, I don't care.
"It's important to solve the situation. This is the most important thing. I must find the solution and I work a lot to find the right solution."
"John is recovering from a bad injury but I don't like to talk about players that today didn't play," Conte said.
"I don't like this. I think this is a lack of respect for the players today who played bad or good."
