Carlow's Padraig Amond sets up dream FA Cup tie with Man City as Newport pull off Middlesbrough upset
Newport County 2 Middlesbrough 0
Newport set up an FA Cup money-spinner against Manchester City by upsetting Middlesbrough 2-0 in their fourth-round replay.
Robbie Willmott and Padraig Amond were the heroes as Sky Bet League Two minnows County - the lowest-ranked side in the last 16 - bridged a gap of 57 places between them and Championship side Middlesbrough on the league ladder.
It was a thoroughly miserable evening for Tony Pulis, who was brought up just a few miles away from Rodney Parade.
But the Boro boss can have no complaints as his side were second best in every department in joining a recent list of Rodney Parade cup casualties that also includes Leeds and Leicester.
Pep Guardiola's side will provide far sterner opponents on February 16, but even the Premier League champions will not welcome the tight confines of this ground and the fervent atmosphere that comes with it.
County's passage to the fifth round for only the second time - the previous occasion was in the 1948/49 season - was confirmed by two second-half goals.
Winger Willmott, having run Boro ragged in wide areas in the first half, opened the scoring two minutes after the break when he advanced 30 yards unchecked through the middle before dispatching a fine finish.
The scorer turned provider midway through the half with a superb move straight off the training ground.
Amond darted away from his marker to reach Willmott's corner at the near post and the clever movement was matched with a ferocious finish inside Dimi Konstantopoulos' near post.
Heavy rain had made conditions difficult but the two sides soon settled down to producing an absorbing tie, played at a frenetic pace.
Jonny Howson fizzed the first opening wide but Boro were fortunate to survive a strong penalty appeal for handball and a goalmouth scramble in the space of a minute.
Konstantopoulos was grateful to drop on the ball on his goal-line after Jamille Matt and Amond both stabbed goalwards without conviction.
The Greek goalkeeper had to be alert again to stop an Amond header looping in at the far post, but Boro were almost ahead when Jordan Hugill raced on to Howson's pass and struck the outside of the post from 20 yards.
But it was County who carried the greater threat and, after Konstantopoulos' face came to the rescue by denying Amond from close range, Joss Labadie just failed to connect with Regan Poole's cross.
Willmott was a constant danger down the right and another fine run and cross from the winger ended with Konstantopoulos pushing out Amond's point-blank header.
Matt sent another header on to the roof of the net and Boro were relieved to get to the interval still level.
But parity did not last for long as Willmott, collecting the ball just inside County territory, advanced to the edge of the area and unleashed a 20-yard drive past Konstantopoulos' despairing dive.
Pulis turned to his bench quickly to make three substitutions but Boro huffed and puffed after County sealed matters with Amond, who had scored the winner in the previous round against Leicester, showing his goal knack again.
Exiles boss Michael Flynn thinks Newport will make £1million from this cup run, with more TV money against City to come.
But, for now, it is all about the glory and County fans were celebrating one of the club's most memorable nights wildly at the final whistle.
Elsewhere, Wolves endured a nervy night before seeing off Shrewsbury 3-2 at the Molineux.
Matt Doherty opened the scoring after 77 seconds, netting from close range after Shrewsbury had failed to clear from a corner.
Shrewsbury levelled things up after 11 minutes when James Bolton headed in from a corner.
Shrewsbury then turned the game on its head, taking the lead against Wolves six minutes before the break.
Josh Laurent's effort was spilled by goalkeeper Ruddy and the ball trickled over the line.
Wolves levelled things up just before half-time, with Doherty heading in his second in added time to make it 2-2. Wolves regained the lead against Shrewsbury after 62 minutes when Ivan Cavaleiro poked the ball beyond Steve Arnold and held on to advance to the FA Cup fifth round.
QPR will join them after beating Portsmouth 2-0 while Brentford held off Barnet 3-1 in their fourth round replay.
