Action from the latest third-round fixtures, with Marine v Tottenham Hotspur, Newport County v Brighton & Hove Albion and Chelsea v Morecambe among the highlights. All three of the Premier League sides would have expected their class to tell against lower-league opposition, but the magic of the cup always suggests that a shock isn't too far around the corner. Plus, action from Barnsley v Tranmere Rovers, Bristol City v Portsmouth, Cheltenham Town v Mansfield Town, Crawley Town v Leeds United and Manchester City v Birmingham City.
