Cardiff City Manager Malky Mackay said his player left themselves with "too much to do" after a poor first half against Newcastle United in which they conceded two goals.
It was the Bluebirds' first match since claiming their first away league win in the top flight in 52 years against Fulham.
"We gave ourselves too much to do," said Mackay.
"If you give a good team time and space as we did in the first half you can be punished and we were.
"We gave ourselves a lot to do.
"We were what Cardiff City is all about in that second half, we were excellent and on another day could have had a point. But we cannot start like that against a good team with good players."
