Newcastle struck late on to get a share of the spoils in the Tyne/Wear derby.
Aleksandar Mitrovic cancelled out Jermain Defoe's first half strike as the game was approaching its closing stages with the result perhaps not being the best for either side as relegation rivals Norwich recorded a win at the weekend.
De Jong told the Chronicle: “Of course they were delaying play because they were feeling that we would score.
“In the end we had a few opportunities to get a chance. Most of the time it was either a block or not enough power or whatever.
“With a bit of luck we could have got 2-1 and we need to continue this next game.”
Newcastle at least managed to stop the rot against their fierce rivals. The draw both prevented a seventh successive defeat at the hands of the Black Cats, and kept them in touch with climbing out of the bottom three in the coming games.
Given that Sunderland missed a chance to put some daylight between themselves and Newcastle, it's probably the Magpies that are in better shape as a result.
De Jong added: “It’s different if you end the game with a goal rather than conceding. Maybe we have a better feeling that Sunderland have after the game.
“We still need to focus on the next one now. They are all important games and unfortunately we could only manage one point.”
Now there is an international break which gives recently appointed manager Rafa Benitez the opportunity to work with his players on the training ground before they travel to Carrow Road to take on another of their fellow relegation rivals in Norwich City - where one feels his side must win in order to kick-start their bid for survival in the closing stages of the season.
