Interim manager Andy Mangan felt Bristol Rovers could have scored more as they eased into the second round of the FA Cup with a 7-2 victory over Northern Premier League side Whitby.

First-half goals from John Marquis, Luke Thomas, Jevani Brown and Antony Evans were added to by substitutes Harvey Vale and Aaron Collins after the break, following Harrison Beeden’s own goal.

“It was one for the neutrals I suppose, but can we take more chances? Absolutely,” said Mangan.

“Can we add more phases of play in their half? Yes. But it’s 7-2 and the last time we scored seven was against Scunthorpe when we got promoted, so there are good omens.

“We’ve got really good players in there, lads who can open you up, lads who can keep the ball and create one-v-one opportunities.

“I thought LT (Luke Thomas) was excellent in his first game back (from injury) and also John Marquis with his endeavour.

“There are loads of positives but as a coach you’re always looking to improve,” said Mangan.

Rovers continue to search for a successor to Joey Barton and Mangan has now won two games from two since taking temporary charge.

Barton’s former assistant also praised 15-year-old Rovers substitute Ollie Dewsbury, who came off the bench with three minutes remaining to become the Pirates’ youngest-ever player in the FA Cup and second youngest in all competitions.

“It’s amazing isn’t it? He did really well with the Under-18s. What a day for him, so proud for him,” said Mangan.

“Can you imagine him going into school on Monday morning, how happy he will be? It will be great.”

Whitby Town manager Nathan Haslam was proud of his side’s efforts against a professional team playing four leagues above them.

“I’m really proud. First half we were a little like rabbits in the headlights, the occasion got to us, which is gutting because we spoke about it a lot,” said Haslam.

“But we’ve just got to take a step back and you know we’re playing a team who are four levels higher. You can see the gulf in class. It’s crazy really.

“We showed them too much respect. We didn’t do our basics well, which I hoped we would, and they punished us. I think they were clinical.

“When you need that bit of luck, there were questions about that first goal being offside. Just to stay in the game, we were on the back foot, and I think that changed the complexion of the game for us really.”

Haslam said of Connor Simpson’s 59th-minute curler into the top corner – the goal of the game: “That one will be played for a long time by Whitby.”

Both managers were angry with referee Simon Mather after Oxford United beat Bristol Rovers 2-1 at the Kassam Stadium in a match that saw three red cards dished out.

Rovers had Jevani Brown dismissed for two yellow cards midway through the second half, and Oxford had two of their substitutes, Oisin Smyth and Stan Mills, sent off in stoppage time.

Billy Bodin and Sam Long scored the goals which secured Oxford’s fifth successive Sky Bet League One victory, despite Aaron Collins’ late consolation.

United head coach Liam Manning said: “It was chaos at the end. I need to see the Mills one back again before I say anything about it because my initial decision is that it wasn’t a red card.

“I was delighted with the win, but I’m not happy with the end.

“We made it hard for ourselves with some of our decisions on the ball and not putting chances away, and we need to be more disciplined – that’s something I’ll have to look at.

“I don’t really want to be talking about the referee, I’d much rather talk about the performance, but the level of refereeing performances in general is not meeting the standards we need.

“And it’s just frustrating that the outcome of some games seems to depend on the referee.

“It was a tough first half. Out of possession we ended up conceding too much of the ball. The one moment of real quality came from Billy Bodin for our goal.”

Bristol Rovers boss Joey Barton felt his side should have had a penalty and that Collins’ disallowed goal in the first half should not have been ruled out.

“I feel severely aggrieved by the referee’s performance,” he said. “We’ll get fined if I tell the truth but clearly anyone who watched that will see there was a lack of control from the officiating team for most of the game.

“I think the officials will look back at this game and, when they are debriefed, there will be a lot of things they’ll wish they did differently.

“Everyone who was here today knows we were the better side. If they don’t, then they don’t understand the game of football.

“We showed who the stronger group is. We had seven or eight missing today. Oxford are a good side on a good run but they are nowhere near as good as us.

“It would have been a great game of football had it been officiated correctly but it descended into a slightly farcical situation.

“I can’t wait to get our hands back on Oxford again at our place. It’s a team we look forward to playing. We have nothing to fear in this division.”

Oxford United beat Bristol Rovers 2-1 in a fiery Sky Bet League One match that saw three red cards.

Billy Bodin finished superbly in the 13th minute to put United ahead.

Controlling Ruben Rodrigues’ chip with his chest to beat his marker, Bodin hammered the ball past Matthew Cox for his second goal of the season.

Rovers were reduced to 10 men in the 63rd minute when Jevani Brown collected a second yellow card for tripping Josh Murphy.

Oxford effectively sealed the points nine minutes from time with defender Sam Long nodding in at close range following Cameron Brannagan’s corner.

Aaron Collins pulled one back for The Gas on 89 minutes, rifling an angled shot high into the net.

Oxford then had two of their substitutes sent off in stoppage time.

Oisin Smyth was given his marching orders for two yellow cards, and moments later Stan Mills was shown a straight red card for violent conduct after a clash with Sam Finley.
