Derby manager John Eustace hailed his team’s performance and was “disappointed not to get the three points” following their 2-2 draw at Ipswich.
Substitute Jack Clarke scored a last-gasp stoppage-time equaliser from the penalty spot as Town rescued a point.
Jacob Greaves gave the home side the lead via a corner after 33 minutes, but former Norwich striker Carlton Morris drew the sides level from the penalty spot in the 50th minute.
Ipswich had claims for what appeared to be a foul in the penalty area by Matt Clark on George Hirst controversially turned down by referee Lee Doughty, and Derby went ahead through a fine strike by Rhian Brewster after 70 minutes.
However, after David Ozoh was adjudged to have fouled Jack Taylor, Clarke stepped up to ram the ball home in the 16th minute of added time to snatch a point.
After four games, both sides are looking for their first win of the Sky Bet Championship with Ipswich, who were relegated from the Premier League last season, dropping to 20th place.
Eustace said: “I thought the first half-an-hour we were excellent.
“We really took the game to a top team and held our own, but we conceded a sloppy goal and when we conceded, Ipswich had some pressure. But we regrouped and came out like we started the first half and scored two good goals.
“Not to see the game out is really disappointing.
“It’s hard for me to comment on what I want to say but to get 14-15 extra minutes that might be a world record for time added, but what an effort from the group.
“For the last 10 minutes, we were under the cosh and defended the box really well.
“You look at the talent they brought off the bench and the way we matched them and defended really well this afternoon, but obviously disappointed not to get the three points.”
McKenna felt it was the “most broken game” he has been involved, despite snatching a last-gasp point.
“There was probably two different phases to the game; it was another step up in performance but the main thing I can really criticise us for is not being 2-0 up with the chances and the territory we are getting,” McKenna said.
“Still in our final execution we really need to turn our domination and a good performance into goals, and then there was the phase after their goal. There’s a lot to learn from it, it shows how quickly a game in the Championship can turn especially against some of the more direct teams.
“From there to the end of the game it was probably the most broken, lowest ball in play that I have been involved in.
“It was barely a football match made worse by a bad refereeing decision that should have given us the opportunity to go 2-1 up, but us conceding a really poor goal on another long ball that we do not defend well enough.
“There was almost no ball in play for most of the time and we were not able to get any rhythm in the game to build any attacks that we wanted to build.”
