United Snap Up New 'Keeper

Zieler, 15, made himself noticed during United's U15 Premier Cup display against Cologne despite beating them along with Kashiwa Reysol of Japan in previous rounds.

Father of the teenager, Raimunt, said: "Despite this gigantic opportunity, Ron-Robert is quiet and remains calm,"

"In sporting terms he gives his best, but he is hardly talking about the subject, he is entirely focused on finishing school." he added

Sir Alex Ferguson continues to search the world for young foreign talent after signing Zieler along with Gerard Pique of Spain and Rossi of Italy.

"We have to look at other parts of the world in order that we can bring players of quality to the club. That is exactly what we are doing and I think there is a similarity between ourselves and Arsenal in that they also realise the handicapping of the Academy system. They recruit from abroad all the time, and so do we. We now have a Belgian, and boys from Togo, Ghana, China, Denmark, Spain, Portugal, Italy and one next year from Brazil. I'm afraid that's what we will have to do because it is important that Manchester United keep producing young players and they come at an age 16 or 17, when development is important" said the Scotsman.
