Chesterfield have sold Tendayi Darikwa to Championship side Burnley for an undisclosed fee after failing in their attempts to tie him to a new contract.Darikwa, who would have been a free agent next summer, has signed a three-year contract at Turf Moor.
Commenting on the player's departure, Spireites chief executive Chris Turner said: "Dean Saunders tried to persuade Tendayi to agree a new deal, but he was adamant that he wanted to leave and submitted a couple of transfer requests. I can appreciate Tendayi's position because he is keen to further his career by playing in the Championship.
"We were left with the prospect of trying to keep an unsettled player for the season, knowing that we would lose him for nothing at the end of the campaign, so we felt that we had to secure the best fee possible in order to move on and grant Tendayi his wish of playing Championship football.
"Tendayi has made an excellent contribution during his time with us and I would like to wish him all the very best for the future."
Darikwa signed his first professional contract in the summer of 2010 and made his debut in an FA Cup tie against Burton Albion the following November. After starting out as a right winger, he was converted to right-back during the 2013/14 season.
The 23-year-old won Chesterfield's Player of the Year award and the Players' Player of the Year award at the end of last season.
