Edgar Davids charts Wilfried Zaha's progress

Edgar Davids has revealed that Crystal Palace forward Wilfried Zaha had developed "bad habits technically" at the start of his career.

The 39-year-old played with the England international for a short period of time at Palace in 2010.

"When I was at Palace, he was a big talent but nothing more," Davids told the Daily Mail.

"He was also developing bad habits technically and no-one was stopping him.

"His end product was very poor at times, but now he is really showing his talent. He has worked hard at his game."

Davids is now the player-manager of Barnet alongside Mark Robson.
