Huddersfield Town head coach David Wagner celebrates his 500th day at the helm today, making him one of the longest-serving managers in the league.

The German joined the West Yorkshire side on November 9, 2015 and has taken the Terriers to the top of the Championship table - an unbelievable achievement given he took control when Town were sat 18th in the league.

Ipswich Town manager Mick McCarthy is the longest-serving manager, while ex-Town boss Simon Grayson sits second in the table with Preston.

Mark Warburton and Gary Rowett are the shortest-serving managers, having both been brought in last week.
