What we need to get the stronger for next season

The season 2011/2012 has been mostly ruined by injuries of our great players. Pato has been injured for the most of the year and Silva got injured on a crucial point of the season. Almost every single player in our squad has been injured more than once during the season.
Why this happens can depend on several things. The Ac Milan medical and fitness staff has gotten critized throughout the season and so has the regular training. For next season several changes needs to be made to prevent injuries.

1. Rotation, many players such as Ibra and Thiago, was forced to keep them self fit and injury free to help Milan. In the end we got punish when both players showed fatigue. Ibra and Thiago are irreplaceable, but player's such as Maxi Lopez, El Shaarawy, Yepes could have play more during the spring.
2. Get new medical and fitness staff, but keep some staff who knows the players well and can easily identify the player's progress throughout the years.

What we really need at the moment is new quality players to replace; Nesta, Zambrotta, Van Bommel, Gattuso, Seedorf and Inzaghi. All top players and legends in the club which will be very hard for Gallani to find replacements to. If we start from the back we know that we have a big room to fill after Nesta. Nesta, one of the best central defenders of his time needs a good replacement. Many options has come up, but some that I think would be suitable as the replacement is the following: Dede ( Vasco Gama) and Fransesco Acerbi (Chievo). These guys are two talentful central defenders that we can get for a fair price. At the moment we have Mexes - Silva as our current starters who are very experienced pair, but either Dede or Acerbi could easily learn from this guys and soon challenge for a starting position.
Left back position has always been an issue these past years. We haven't had a good left back who could combine defence with attack. Antonni, Mesbah, Taiwo and possibly Didac are our current options for that position. Taiwo will most like leave and Mesbah hasn't been successful since joining Ac Milan in January. It is hard to find a quality left back in the world, but a more defensively minded left back is needed on our current weak spot. Let's hope that De Sciglio will be our future left back star as he impressed me in the Inter Vs Milan game. Hopefully he will play this season and impress us even more.
In midfield we have lost plenty of players. To replace, Van Bommel, Gattuso and Seedorf won't be easy at all. At the moment we don't have a good defensive minded midfielder such as Van Bommel. It has been say that Witsel from Benfica is interesting. For Gattuso, Lass Diarra is a very good replacement and at the moment I think we can get him for a good price from Real Madrid. He impresses with a non stop running and well timed tackles. Nuri Sahin from Real Madrid has also been named as an option but it is unsure whether Real Madrid believe in him or not. If they don't Milan can focus on main Nuri a Rossoneri. We also need a good back up to Boateng, the offensive midfield position, there was no real back up to Boateng last season and that was hard for Milan. Ganso (Santos) has been named as an option and I agree that he would be great at Milan but he needs to come at a fair price, we are not going to over pay money for a player who hasn't really showed what he can in European leagues.
We have one of the best attacks in the world, we have world class players such as; Ibra, Cassano, Pato, Robinho and El Shaarawy. We need no changes here. We were unlucky last season because of injuries to Pato and Cassano which destroyed their season and Robinho wasn't in good form. We know what this strikers can do so we don't need any changes here.
If we make all this changes I am sure we can fight for all three mayor titles.
