Welsh club Newport, who are 14th in League Two, forced a replay at home to Middlesbrough after scoring an injury-time equaliser in a 1-1 draw at the Riverside over the weekend. Newport beat Premier League opponents Leicester in round three and could book a clash with Pep Guardiola’s City if they upset Boro in next week’s replay.
