Paulinho - better creativy, flair
Flair? Paulinho rarely uses any kind of flair he may possess.
David Luiz - better positioning, concentration, technique, long shots, heading, strength, stamina, passing, creativy, first touch, dribbling
Long shots, dribbling and strength of David Luiz seems some what fine for me, there's a great gap between him and T.Silva for example.
Ganso - better stamina, natural fitness, pace, acceleration, balance, strength, agility
Ganso has terrible stamina, acceleration and natural fitness. He's also weak and slow. He compensates these "low stats" with great technique.
Romarinho (Corinthians) - contract to June 2016; salary: 15.000€ per week. (better team work, bravery, positioning, work rate, concentration, creativy, off the ball, determination, flair, agression, decisions, pace, strength, stamina, natural fitness, balance, finishing, heading, long shots, dribbling, crossing - he reminds a Brazilian Thomas Mueller) preffered foot: Booth
Romarinho is playing well for Corinthians, but he's not to be compared with Thomas Müller. Increasing his stats will make necessary to increase the stats in hundreds of players in brazilian league. He's a medium (to low) quality player, only in a good momentum and with a balanced team helping. Also, he's horrible with his left leg.
