Manchester City academy manager Jim Cassell admits the stakes have been raised at his level following the takeover in the summer.

Cassell feels they will have to extend their horizons even further because of the club's high profile.

"It looks as though we are going to have to produce world-class players, if you like," he told BBC Radio Manchester. "That is the challenge.

"It can be done but it might take longer and people might have to be more patient.

"We might have to up the quality and spread our net scouting wise to broaden the field a bit."
