Southampton boss Mauricio Pellegrino insists Manchester City can be defeated as he prepares to take on the unbeaten Premier League pacesetters.
Pep Guardiola's free-scoring side have produced some sensational performances so far this season, winning 12 and drawing once to open up an eight-point gap over second-placed rivals Manchester United.
City, however, needed a lucky late winner from Raheem Sterling to scrape past Huddersfield on Sunday and Pellegrino believes that game shows it is possible to take points off them.
'Nobody is unbeatable in football and in sport,' Pellegrino said ahead of Wednesday evening's clash at the Etihad Stadium.
