Attributes for Wingers;
Pace, Acceleration, Off the Ball and Crossing.
The rest less important. Remember, the lower Teamwork, the higher Dribbling must be.
Can't come up with names, though. Beckham is the best crosser in-game, but slow, not a real dribbler, more team player. I tried buying him thousands times, he refuses again and again. He is getting older, and the chance of him playing good is getting worst. I manage R. Madrid, never bought players, try to sell and develop my own, the A. Wenger Style, very challenging. Arjen Robben is an excelent winger, though, his crossing sucks like ****. I just looked at average ratings of C. Ronaldo and Messi, both above 7, but shocking amounts of assist. For assist I strongly recommend Guti before aged, he gave my team 29 assists first season in 43 app.
