Why does Real want another striker?
They already have Raul, Van Nisterlooy, Saviola, Baptista on the books. Let us not forget Robinho is really a center-forward that is being forced to play on the wings. I saw Baptista playing couple of times in this summer, and he looked razor sharp. If given chance, I think he will bang in fair sum of goals.
On aging players, well I agree with Ahmed.
Yes, players don't improve but class is always permanent. Players like Del Piero, Cafu, Figo, Zizou just dont forget how to play this game, overnight. They do deterioate but given the standard they already at, they are still better 99% of players out there. Seriously, who in right fame of mind would rather start "young" Djibril Cisse, instead of "old" David Trezeguet. In Super-Coppa Italia, Figo comes on and instantly changes the complexion of the game with wonderful vision, and skill. Of course, I want young players in the team, because they bring enthusiasm, and hunger which old playes rarely have. Furthermore, young players represent valuable FINANCIAL investment. When teams buy and sell players, they are not done for strictly winning purposes. Trezeguet probably reached a point of career where we won't get a fair value on his services by selling him. If we had to sell him, it was last year, and we kept him. There is simply no way you are going to replace David's quality with similar sum, considering likes of Darren Bent (who I havent really heard of until this year) gets something like 23-25m Euros.
On Hunter and Trez, I think they can play together. I am not Hunter expert, but quick glance suggests he has deceptively good touch, and decent speed. It wont be pretty to watch, but in the league against inferior opposition they will score a lot of goals, which is what you need if you want to come out on top.
