Best one
IMO bar none is Franco Di Santo. I have wrote about him a few times.
Get him for pennies (relatively) from Audax Italiano and he starts the game aged 17. He is alomost ready to go as soon as you buy him but just bring him in steadily over the first season and you will have a fantastic Striker. He is good in the air, strong, can dribble and scores for fun.
Somehow managed to get him for my IFK Goteburg team at the end of 2nd season. I have won the title in my third with 2 games to go and he has bagged 34 goals so far. Play him up front with a quick forward and he is electric. Headers, long shots, one on ones.
Got him for 750k compensation in this game but I have had him for Ajax, PSG and he is awesome.
He is Argentinian by the way and chelsea and manure etc are sniffing about IRL for him. He has however unfortunately been labelled as the new Maradonna. Strange comparison considering he is 6 foot 3
