Des Buckingham singled out Josh Murphy after League One Oxford saw off last year’s FA Cup giant-killers Grimsby 2-0 at the Kassam Stadium to reach the third round.

Murphy made the first goal – converted by Marcus McGuane – after 11 minutes, with substitute Billy Bodin heading in the second from Cameron Brannagan’s cross 15 minutes from time to give Buckingham his first win in charge.

He said: “The whole team were very good – the one player who maybe really stood out was Murphy on the left-hand side.

“He is one of many in the team who are keen to show me what they can do and I thought he had a wonderful game.”

Buckingham, who swapped 35-degree Mumbai for sub-zero Oxford to get his first shot at management in England, added: “What pleased me most was the professionalism in how we approached the game.

“It was a professional performance from us against a team that’s also desperate to impress because they’ve got a new manager as well.

“There might have been a perception after playing Bolton on Tuesday night that we would take our foot off the gas here but I didn’t see that at all.

“I saw a very well organised and disciplined team.

“It finished 2-0 but I think we could have scored a couple more.”

McGuane followed up to score when Mariners goalkeeper Harvey Cartwright could only parry Murphy’s shot – after the winger had sprinted 60 yards up the left on a break from defence.

It all came from a Grimsby corner that was poorly executed.

And new boss David Artell, who has been in the job for less than a week, blamed himself for the goal.

Artell said: “I blame myself for it because it came from our corner – and we haven’t worked on any set-pieces, which is my fault.”

He added: “When you’ve only had one proper training session and two match-prep sessions in a week it’s very hard to change a lot.

“But I thought we gave a good account of ourselves, we controlled possession better than we did on Tuesday night at MK Dons.

“I’ve seen enough to know that we’ve got a lot of qualities and we’re going to be OK.”

Grimsby never got close to repeating their fairy-tale run of last season when they won at Southampton and made it all the way through to the quarter-finals.

Their best opportunity fell to sub Donovan Wilson who ran in behind the home defence in the second half and brought a good save from James Beadle.

The one disappointment for Oxford was seeing forward Marcus Browne, who had been sidelined for three months with a hamstring injury, have to come off the pitch shortly after going on.

Buckingham said: “Marcus has been out for 14 weeks and has been working extremely hard with his rehabilitation.

“He was cleared to play and we put him on and he was ready to go. He contributed extremely well to the second goal but then just suddenly felt a little bit tight, so rather than risk anything we brought him off.”

Des Buckingham enjoyed a first win as Oxford manager as the League One side reached the third round by beating League Two opponents Grimsby 2-0.

The Mariners were unable to repeat last season’s cup exploits when they became the first club in the competition’s history to knock out five teams from higher divisions on their way to the quarter-finals.

Marcus McGuane fired Oxford ahead in the 11th minute and Billy Bodin got the second 15 minutes from time.

Grimsby were the architects of their own downfall as Oxford’s opener came from their own corner. Josh Murphy raced 60 yards and although Harvey Cartwright parried his drive, McGuane followed up to score.

Otis Khan had two half-chances for Grimsby in the first half and with 20 minutes to go Donovan Wilson was denied by James Beadle’s low save.

Cartwright was much the busier, saving from Stan Mills, twice, and Ruben Rodrigues. The visiting keeper also saved superbly from Bodin and Tyler Goodrham’s drive.

But he could do nothing to stop Bodin nodding in Cameron Brannagan’s chipped cross in the 75th minute to seal Oxford’s progress.

Slough player-manager Scott Davies was proud of his players despite their 7-2 FA Cup first-round replay defeat at the hands of League Two opponents Grimsby.

For an hour of the game the Rebels were well in the tie at Blundell Park, but once the Mariners were able to get back ahead, there was no looking back.

There was disappointment from Davies after the game that the cup run was over and that the game had ended in such a fashion, but he also spoke with pride as he reflected on his team’s journey.

He said: “I’m extremely proud of how far we’ve come – Hayes and Yeading, Salisbury, Ebbsfleet and then taking Grimsby to a replay.

“For 60 minutes I didn’t think there was much in the game, but the manner of the defeat in the end looks bad.

“I don’t think the final score represents the performance. I think, for the first 20 minutes of the second half, we were absolutely brilliant and I thought the goal was going to come and when we didn’t get it, it is obviously a big disappointment.

“I’m immensely proud of lads still but I was disappointed in the manner of some of the goals we conceded because I think there were a few of us that gave up.

“There was emotion in the end in knowing the cup run was over and that bled in towards the end of the game.”

For Grimsby, the search for a complete performance goes on for interim bosses Shaun Pearson and Ben Davies, but back-to-back victories is a good response to their poor display in the first game against Slough.

Pearson said: “That was probably the least one-sided 7-2 ever. It was a really tough challenge, but we knew it would be going into the game anyway because Slough have been on a good run of scoring goals.

“We know from last season from being on the underdog side of these types of games that it’s not always easy as the bigger team to go out and win, but we’re pleased to win in the end.

“We’re pleased with a lot of things – the fact we’ve scored seven goals is obviously the big positive and some of our attacking play was brilliant.

“We didn’t have control of the game at the start of the second half but we put bodies on the line and that’s what you have to do sometimes.”

Grimsby fought through an end-to-end first half to beat sixth-tier Slough 7-2 in their FA Cup first-round replay at Blundell Park.

The Mariners opened the scoring in the seventh minute as Arthur Gnahoua’s deflected effort on the edge of the Slough area fell to Rekeil Pyke to finish neatly.

Slough went two down in the 16th minute, with Danny Rose diving in to finish off a corner that was flicked on at the near post.

The Rebels pulled a goal back in the 19th minute – Tyrese Dyce heading in at close range – and Grimsby’s lead was completely erased in the 33rd minute by David Ogbonna.

The hosts restored their advantage in the 45th minute as Pyke headed in from six yards and they then added a fourth goal in the 65th minute through Gnahoua.

Alex Hunt came off the bench for Grimsby to remove any doubt of victory for his side as he finished off a nice team move in the 79th minute.

Gnahoua set up the fifth and scored the sixth six minutes later from a similar position, shortly followed by a seventh from Jamie Andrews.
