It was the Dutchman’s uncharacteristic mistake which allowed Troy Deeney to score what proved to be an ultimately decisive goal as United were knocked out of the FA Cup against Watford on Saturday.
A fourth-straight 1-0 defeat led to fans chanting their displeasure from the stands - including “We want our money back” - and top-scorer Wijnaldum emphathises with the travelling Toon Army.
Newcastle are languishing in the Premier League relegation zone and Dutch international Wijnaldum knows it is crucial they give the supporters something to shout about against Man United at St James’ Park.
“Yes, of course (we understand the fans’ frustration),” the 25-year-old said.
“We saw how much the supporters were hurting (at Watford). How I see it is that they want something back, and that is normal.
“But still I hope that they will be there at the next game and support us.
“We need that. It’s a tough period and a tough situation, and the help of the supporters is very important for us now. The situation is not so easy – it’s very difficult.
“I understand the anger of the supporters, but we need their support until the end of the season.”
It is now 412 minutes without a goal for the Magpies and Wijnaldum is not shying away from the fact that putting the ball in the back of the net is United’s problem at the moment.
He also knows that it is time to put a smile back on fans’ faces by getting a result against Man United though.
“We must give them something back,” Wijnaldum added. “We must take the chances we get, then it will be easier for us to win games.
“We have been creating four or five games each game. That’s what we must do to make it easier for ourselves.”
