I prefer them to be older. Cech is going to be the exception, because Abbiatti is getting on my nerves lately. Usually i dont have good experiences with young GK's. They always tip the ball inside or rush out like morons to get a ball and leave the opposition with a open net.
Made a few signings (spent a ****load of money aswell) for my Man Utd side : Cech (£ 13 m), Rooney (£ 37 m, ho ho ho!), Adu on a free, Matt Hill on a free, David Evans (17 year old defender with kick ass stats, £ 3.3 m) and Mario Nicoletti (same as Evans, £ 700K), and Sculli on a free.
Sold a few players aswell : Ruud (£ 6 m), Nihat (£ 10 m), Breinburg (£ 5.5 m), from the top of my head. Wohoo! £ 37 million for Rooney! I'm more stupid than Man Utd IRL.
