I'm surprised people have had such bad luck on the game. I found this one a little late, about 6 months after he'd appeared. 26 million I payed but worth every penny. The guy is a beast infront of goal.
Also had this guy come through my youth academy, you certainly need a bit of luck in that respect. He's classed as a wonder kid and he only turned 17 not long ago. I got Aguero to train him and change his mentality to driven, determination = 20. It should help his development as well as his match performances as a result.
I had a thin squad but managed to win the Prem, FA Cup and Champs League this year. Liverpool have been **** tough to beat but I have figured out how to play them. 4-1-4-1. Starves Gerrard and Torres of space and time, Liverpool literally are a two man team lol

For finding regens, just need to throw a few filters in and have some basic knowledge.
1. English regens come in on 24th July soon as you are set targets for the new season. Other countries vary but this is when the game is populated. Gives you an idea of when it's best to hunt for fresh talent.
2. Value is normally reflective of potential at this early stage, if you have to pay a high compensation cost you more than likely have someone who will make it with training.
To search for them I filter out anybody above 21, and put a value criteria of "must be more than" 500,000-1 million in value. Then sort via attribute to see who has got the starting stats. Some have potential but are too poor to begin with.
It takes a while for some regens abroad to come under your scouting scope. If you don't hide attributes it's well worth taking a look at academies & first teams of major clubs. They'll have some 16-18 year old talents in them most likely.
