Manchester United boss Sir Alex Ferguson wants to keep hold of his two young goalkeepers Tom Heaton and Ron-Robert Zieler.

The Telegraph says Ferguson is more bullish than ever about the strength in depth he has in the goalkeeper position. After his first three goalkeepers, the Scot has been impressed with Heaton's form on loan at Cardiff and is also excited about the Germany Under-19 player Zieler.

Zieler has just signed on-loan with Northampton.
