Sergio Aguerro (Kun Aguerro) who plays for Athletico Madrid, you should be able to aquire him for around £10,000,000. He is 20 years of age with an overall of 85. He is very quick and his finnishing is seccond to none, after a few seasons at a good team he can be turned in to a very good player, and if the time comes to sell him you could make three or four times what you paid initially.
If the first thing you go on is Pro season mode on semi-pro difficulty and you think like me you think getting exoerience points is a breeze and very quick to get then don't think that when coming into manager mode if you are doing what I done then you'll find all the details for that on forums at the Gemeral Playstation 3 on Pro challenge 5 which is my series of posts and then come back to this hint it takes twice as long to get twice as long to get the players to top form as it would in Pro season.
Firstly, you must pay attention to your signings. If you are in Coca Cola league 2, then go to transfer central, search, detailed. The filter you will want is: Min value 60-65 position: whatever you need, transfer status: listed.
Next you have two options. You can either pick whatever you want, or harvest some young talent by setting age to 20-23. There will normally be plenty of players up for grabs. Replace your worst players first and work your way up. If a high profile player (say overall 72) is on sale for the amount you can afford to spend, buy him. Next, seeing as you are in a low division and these generous sponsorships that FIFA give us give you way above your current wage bill, you will want to be putting the player wages that you want to buy to maximum. When you are done refurbishing your team, play/sim about 5-10 matches. Build up money,basically. Then, go to office, staff upgrades, fitness. You want him up to at least 8. 10 preferably as it means your players are fully rested for every match. Enjoy success
