Feyenoord have asked a local university to evaluate their training methods after Tim de Cler became the latest of the club's players to suffer a hamstring injury.

De Cler limped out of the 1-1 draw at Vitesse Arnhem in the 84th minute, and Feyenoord coach Gertjan Verbeek is waiting to learn how long he will be sidelined.

De Cler joins a long list of Feyenoord players to suffer a hamstring injury, following Denny Landzaat, Jonathan de Guzman, Michael Mols, Andwele Slory and Luigi Bruins, and the club will now work with the Erasmus University Medical Centre in Rotterdam to determine how the club can prevent such problems in the future.

"As a coach your heart misses a beat everytime a player grabs his upper leg," Verbeek said in De Telegraaf.

In addition to assessing training, Erasmus University will also look at Feyenoord's treatment methods, as several players have suffered recurrences of their injuries during their comebacks.

"We also want to look at the way we bring players back after such an injury," Verbeek added. "Some players have got injured again at the end of their recovery process. Maybe we must change something about what we do."
