Newcastle's U21s failed to build on their fine 4-3 win away to Aston Villa losing both a man and a goal in the closing stages of their PL2 encounter with Arsenal at the home at Boreham Wood on Friday.

Caretaker coach Robbie Stockdale took charge of the side once again and the game was scoreless until last week's hat-trick hero Matheos Ferreira was shown a straight red card by referee Emily Heaslip in the 80th minute.

The ten-man Magpies then were denied a point in the last minute of added time when visiting goalkeeper Aidan Harris saved a penalty from Andre Harriman-Annous, only for the Arsenal striker to react quickest and nod in the rebound.

A closely-contested first half saw Harris make a fine stop with his feet to deny Brando Bailey-Joseph, while United's Michael Mills shot against the upright six minutes after his half time arrival from the bench. Then came Ferreira's dismissal for an over the top challenge on Callan Hamill on the touchline.

United held out until the sixth minute of added time when Logan Watts brought down Harriman-Annous inside the box and he got up to convert at the second attempt.

The defeat saw United drop to 24th place in the 29-team league with 12 points from 13 games.
