First half goals from Nic Gibson, Zoe Creaney and Phoebie Poole were added to by Zoe Barratt in the closing stages.

The U’s made the breakthrough five minutes before the break, when Gibson headed home Kate Wiseman’s free kick.

United then blew apart the visitors, as Creaney smashed in from a corner, while Poole fired in from the edge of the penalty box.

Four minutes from time, a rocket from Barratt completed the scoring for the U’s.

United manager Sam Rose told the club website: “It’s been a tough week with three games and two training sessions, which is more than the girls usual have to do, so to come away with a win in the cup and two in the league is really pleasing.

“It wasn’t pretty, but we kept a clean sheet and scored four goals, so I don’t think you can ask for too much more at the end of a long week.”
