Liam Delap's exceptional goal-scoring display helped Ipswich earn their first home win of the season, beating Chelsea 2-0 as the Blues' title hopes dwindled.
After scoring a 12th-minute penalty, the 21-year-old striker set up former Chelsea winger Omari Hutchinson's second eight minutes after the break.
Chelsea dominated possession but were wasteful and the video assistant referee (VAR) ruled out a Joao Felix first-half equaliser after a long check for offside.
Earlier, ex-Manchester City striker Delap powered in a penalty that he won himself after VAR judged that there was "sufficient contact" by goalkeeper Filip Jorgensen after the Ipswich man had dribbled past him.
