Trippier started his career in the youth system at Manchester City but failed to make the breakthrough to the first team and didn't make a professional appearance. In February 2010, he joined Football League Championship side Barnsley on a one-month loan. He re-joined the club in August 2010 for a six-month loan which was later extended until the end of the season. In July 2011, he signed for Championship side Burnley on a season-long loan which was made permanent in January 2012 for an undisclosed fee, signing a three-and-a-half year contract. He was named in the Championship PFA Team of the Year for two consecutive seasons in 2012–13 and 2013–14. In 2014 he secured promotion with Burnley to the Premier League as the side finished runners-up in the Championship. He has also represented England at all levels from under-18 to under-21, featuring in the 2009 UEFA European Under-19 Championship and 2009 FIFA U-20 World Cup.
