Goalkeeper Petr Cech has admitted Chelsea suffered a hangover from surrendering the Barclays Premier League title in their disjointed draw with Newcastle.
Carlo Ancelotti's new-look Blues failed to lay down an early marker for next season in a flat display, which came 24 hours after they were deposed as champions by Manchester United.
There was a sense of transition during Sunday's 2-2 draw, with Chelsea parading their new kit and manager Ancelotti making six changes which seemed to hint at next season's line-up.
Cech said: "It seemed to me that in each of us there was still disappointment from not winning the title, as on Saturday Manchester United captured it.
"We wanted badly to win the last match of the season at Stamford Bridge and conceding in the last minute is not the best way to reward our fans, who have supported us all year.
"It somehow sums up our season in the way that there was always something missing for us to finish the job."
Cech insisted it was not all doom and gloom, adding: "Despite the bad result, I found two positives in it.
"The first one was that Arsenal were beaten, which means we have definitely secured second place in the league.
"The second positive is the performance of our young midfielder (Josh) McEachran. He started the game and did really well."
