Ronald Koeman unhappy with Manchester City star

Manchester City's young striker John Guidetti has been criticised by Feyenoord manager Ronald Koeman.

The Swedish starlet, who has scored 19 goals in 21 appearances on loan at the Eredivisie club, has been blasted by Koeman for being selfish.

"John may be best to work harder in the field," said the former Dutch international. "And furthermore, he must be less concerned with his own game and more about Feyenoord."

Guidetti, 19, joined Manchester City from Stockholm-based Brommapojkarna in 2010.
