On a pitch unlike any other we’ve played on this season, we found it difficult at times to impose our usual passing game. Rodney Parade, also home to Newport RFC and the Dragons, has hosted 61 matches this season, leaving the pitch full of divots and bereft of grass. City, usually so quick and slick, were stymied by the conditions, unable to string together sustained periods of possession.
Fernandiho and Danilo went close with long-range efforts, and Leroy Sane clipped the top of the crossbar after a brilliant one-two with David Silva, but the first-half brought few clear chances for the Blues.
And City’s lead was doubled when Phil Foden offered the latest example of his precocious talent, weaving past Dan Butler before beating Day at his near post.
But Newport managed a famous goal to halve the arrears with just two minutes remaining. A long ball caused havoc for Aymeric Laporte and Nicolas Otamendi, allowing Padraig Amond the chance to lob Ederson. It was a fine finish from the Irishman.
Lesser teams may have retreated, with the threat of a long-ball siege weighing heavy on the mind. But City did nothing of the sort.
Winning the ball high up the pitch, Sane took the ball away from one before slipping in Foden, who breezed past O’Brien before unleashing a devastating effort into the top corner.
Mahrez added a fourth, collecting Stones‘ pass and cutting in from the left to lash it home, completing a frantic final period.
