Tottenham Hotspur slipped seven points off the pace last weekend.
Mauricio Pochettino's side went down 2-1 at Stamford Bridge in a defeat which leaves the Lilywhites seven points behind the Premier League leaders - and four behind Arsenal in the race for Champions League qualification.
Christian Eriksen had given Tottenham an early lead, but goals either side of half time from Pedro and Victor Moses flipped the match on its head.
Spurs were arguably the better side in West London and King felt a sense of disappointment at full time, but highlighted the midfield performance of Dembele and Wanyama - who helped Tottenham record 54 percent possession - as positives.
“It was disappointing to see us play so well and not get the result,” he told Tottenham's website. “We started really well, controlled the game, Victor and Mousa won everything in midfield and Chelsea were struggling with us.
“To concede that goal right on half-time was a real blow. You sensed Chelsea would come out a better side after that and they had a spell where they scored again and looked dangerous.
“We needed to stay in the game, did that and worked our way back into it but couldn’t create that one more opportunity. We were the better side for long periods and we have to take positives from the performance.”
Consequently, Tottenham remain with just one victory from their last 10 matches in all competitions and it is dangerously close to using the word 'crisis'.
They could, and probably should, alleviate some pressure on themselves this Saturday when Swansea City visit North London, but a tricky trip to Manchester United lies on the horizon the following week.
