Different clubs adopt different policies. The modus operandi of AC Milan over the past few years has been strange. The Rossoneri bought players who were in the twilight years of their career and in the process failed to build talented youngsters.
At the moment, Milan is facing a crisis situation with half of the team in their 30s and well past their prime.
The team is not only struggling in the domestic competition but also their European dominance has attenuated.
The latest rumors suggest that AC Milan aren't happy with the number of golden oldies in their roster and are in search for more to make the situation even more worse.
Manchester United striker Dimitar Berbatov is on the radars of Milan and this signing, if it goes through, is not going to help the Rossoneri.
The 29-year-old striker has been less than impressive for the Red Devils since his £30 million move from Tottenham in the summer of 2008. He has struggled and the recent team selections show that Sir Alex Ferguson has lost faith in him.
Fergie is comfortable with a half-fit Rooney over a fully-fit Berbatov, which speaks volumes about the recent form of the Bulgarian striker.
He's well past his prime and not the best option for a world-class team that is on the lookout to reduce their average age. Berbatov could be available for as low as £15 million but that cash can be utilised judiciously elsewhere.
The Italian giants are viewing Berbatov as a possible replacement for Klass-Jan Huntelaar but the former is even worse than the Dutch striker. There are so many younger and better options available for Milan to revamp their ageing squad and the addition of Berbatov is only going to take them two steps backward.
Fergie will be looking forward to accumulate as much cash as he can to fund the big signings that he's planning for the summer. And the first player to leave may be Berbatov but Milan shouldn't make the mistake of bringing him to Italy.
Should Milan offload Huntelaar and sign Berbatov?
