Fred is certainly quick, and one thing he does that I don't remember Les Barrett or Jimmy Conway, or Tosh or Johnny Key doing that much is he cuts in behind the full-back, beating him for pace rather taking the ball to the by-line to cross, or cutting inside to shoot,like Boa.
This is very important in breaking down teams that defend deep. And Fred has the beating of most defenders for pace, and must be a nightmare to play against. He's definitely become a very important player to us.
Hard to say who is fastest, but Fred seems to turn on the rocket boosters to accelerate past defenders in that crucial few yards that take him to the by-line, and in behind his man ,and give him the opportunity to pass to an incoming Fulham player - he is one of the fastest I've seen over fifteen to twenty yards or so..
