"I don't think we're a long way away from the teams at the top," Jones told the club's official website. "You look at our first half performance and barring the two goals we conceded, we were fantastic.
"If Chelsea are one of the best two or three teams in the country, then I think you have to say we can be right up there alongside them – our performance in the first half proves that.
"We're not a million miles away, I'm telling you, but we need to stick together if we're going to turn it around."
