The 29-year-old has frequently played well for the Blues this term, although his last appearance was a game to forget.
He was sent off as Chelsea lost a rare Premier League game against Tottenham and was handed a one-match suspension.
Terry missed their 7-0 win over Stoke, but has rejected claims his form has not been up to its usual sky-high standard.
With the amount of games the modern day footballer plays, Terry insists it is only natural to have the odd bad outing.
"I'm totally fine with my form. For England, I think my performances have been very good right through the World Cup campaign," explained Terry.
"And, contrary to what everyone else is saying, my form is fine for Chelsea as well.
"If I'm going to play 50 or 60 games I'm expected to have one, two or three bad games.
"That's standard - you are not going to play well every game. Not even Wayne Rooney and Lionel Messi can do that.
"It's inevitable you have bad games, it's all about how you respond and I think I've responded well."
Meanwhile, Terry believes keeping their experienced players fit will be crucial to England's hopes of World Cup glory this summer.
The likes of Rio Ferdinand, Steven Gerrard and Frank Lampard all have an abundance of caps between them and Terry believes they are in their prime.
Terry has also been enthused by Wayne Rooney's ability to perform week-in, week-out for Manchester United up front on his own and believes England can go all the way this summer with a bit of luck.
"I think we've got players in their prime, actually," he continued.
"When you look through the spine of the team we've got people like David James, Rio, Stevie G, Frank and Wayne, who's shown an awful lot of experience on his own up front for Man United this year.
"If we can keep these players fit through the tournament then with a bit of luck I think we have a good a chance as everybody."
