Burnley landed Chesterfield’s Player of the Year in the summer of 2015.
The highly-rated defender signed a three-year-deal, with a further year’s option in the club’s favour, after the two clubs agreed an undisclosed fee.
The Clarets beat off strong competition for the Nottingham-born full-back, who started his career at Chesterfield and penned his first professional contract in 2010.
After making his debut in the same year against Burton Albion in the FA Cup, and following as loan spelll with Barrow, Darikwa began to establish himself as a first-team regular at the Proact Stadium.
He was an integral part of the Spireites side that won the League Two title in the 2013/14 campaign, after being converted from a right winger to a right back by former boss John Sheridan.
His blossoming talent attracted interest from a number of clubs and in the 2014/15 campaign his stock continued to rise.
He made 56 appearances in all competitions as Chesterfield reached the League One Play-Off semi-finals, where they lost out to eventual winners Preston North End.
At the end of the season awards, Darikwa picked up four gongs including the Player of the Year and Players’ Player of the Season.
The 24-year-old made his full Clarets debut against Leeds United at Elland Road and provided the assist for Sam Vokes' leveller in the 1-1 draw.
He continued to impress at full-back in the 2015/16 season, making 24 appearances and scoring his first goal at Championship level against Reading.
