Burnley boss Sean Dyche believes Steven Defour could have become one of the Premier League's best players if he had not suffered several injury setbacks.
Defour left Burnley after player and club came to an agreement to cancel the last 10 months of his contract and he has subsequently joined Antwerp in his homeland.
The Belgian joined Burnley in 2016 for £8million from Anderlecht and showed his quality on more than one occasion with his free kick in the draw with Manchester United in 2017 a particular highlight.
But the midfielder suffered with injuries throughout his three year stay at Turf Moor, playing 56 times for the club.
The 31-year-old had not featured for the Clarets since the FA Cup defeat to Man City in January and although he returned to training over the summer, he has not been fit enough to make a matchday squad.
And Dyche said it was a decision that made sense for all parties.
"I think it was a number of things, his personal situation, his injury situation, the club wanted to do the business side of it," said the Clarets boss.
"It is a shame because he was playing so, so well when he got the injury initially (in January 2018), the main injury on his knee. He played on and finished a game with a good chunk of bone and cartilage that had come off the bone more or less.
"Then he had to have an operation and a recovery period and unfortunately on the back of that he has had problems with his calfs. It has been really tough for him because he is a great lad and we wish him well.
"It is shame he has had the windows he has had at Burnley Football Club because I believe if he as fit all the time he would have turned into a very, very good Premier League player and a consistent performer in the Premier League because he is a highly talented player."
