Matty Godden scored a brace as Championship Coventry thrashed League One Oxford 6-2 at the CBS Arena in the FA Cup third round.
The substitute followed up early strikes by Joel Latibeaudiere and Ben Sheaf, while Kasey Palmer’s thunderbolt made it 3-1.
Callum O’Hare’s second-half penalty made it 4-1 to the hosts who are through to the fourth round for just the second time in six seasons, with Mark Harris and Tyler Goodrham on the scoresheet for Des Buckingham’s side.
A frantic opening saw four goals in the space of eight first-half minutes, sparked by Latibeaudiere’s near-post header.
Coventry enjoyed the lion’s share of possession in the early exchanges but Oxford were level almost instantly when Harris latched on to Palmer’s mistake and a wicked deflection off Luis Binks took his effort past a helpless Ben Wilson.
The 1987 FA Cup winners were back ahead even quicker than they had been pegged back when Ellis Simms powerfully drove to the byline before squaring for Sheaf to slam home his second of the season.
Palmer then gave the Sky Blues daylight when he picked up the ball inside the Oxford half before uncorking a 30-yard rocket into the top corner to round off an exhilarating first 17 minutes.
The U’s went out of the cup at the same stage last year after a 3-0 defeat to Arsenal and could have found themselves further behind when Simms blazed over after outmuscling a U’s defender, whilst Milan van Ewijk’s free-kick cleared the crossbar.
Mark Robins, who won the FA Cup as a player with Manchester United in 1990, could have seen his side go three goals to the good immediately after the interval when Palmer played in O’Hare, but he was thwarted by Simon Eastwood.
O’Hare was given a second chance to give the Sky Blues the three-goal lead they deserved after Ciaron Brown fouled Palmer before Coventry’s talismanic midfielder made no mistake as he sent Eastwood the wrong way from the spot.
Palmer was at the heart of all of Coventry’s attacking play and created the Sky Blues’ next chance for Jake Bidwell, who slid his effort past a post.
Oxford, backed by around 3,000 fans in the West Midlands, sensed hope when Goodrham picked out the bottom corner from the edge of the box, but that hope was dashed soon after as Godden entered the fray.
First, he took down Jamie Allen’s lay-off and bent an effort into the far corner before picking out the same corner with his left foot five minutes later to finish off the rout and book Coventry’s place in the fourth-round draw.
