Terry was left unimpressed by Chelsea's players for defeat at Leeds United this week.
He posted to social media: “What a poor performance that was. Everything I said about Leeds away is they’re going to be aggressive, the fans are going to be up for it, the fans are going to be hostile.
“You either have to match them or you go and take the sting out of it completely and we certainly didn’t do that in the first half.
“We showed glimpses in the second half when (Pedro) Neto comes on and gets back in the game at 2-1 but we can’t perform like that.
“We can’t follow two unbelievable performances against Barcelona and Arsenal because it’s certainly not going to make you title contenders at the end of it.
“That’s what’s going to cost us at the end of it, we’re inexperienced and if you can’t go Leeds away and know what to expect. You need to go there and show the fight and match Leeds in every single way.
“You need to earn the right to play and after 15, 20 minutes then you play your football. We didn’t do that and that’s going to cost us.
“We’ve got Bournemouth away and some tough away fixtures coming up which are only getting tougher. We need to find a way to deal with that.
“Even when I played you know Leeds away a fight is on your hands right from the word go. You need to make sure everyone’s up for it.
“Goal from a set piece, individual mistakes, defensively there were mistakes. Clearly not good enough.”
