I was only able to catch bits of the first half and rest I was following in match thread. At least from what I caught, he seemed like an absolute dynamo, making interceptions and getting around the pitch. The match thread though was so many posts about his bad passing.
In the end though - first goal, his energy wins the ball to setup Pogba for playing in Greenwood, second goal first time pass to Bruno who then releases Rashford, 3rd goal - ball played long, Fred is in our half past the circle, as ball is headed, he anticipates the ability to win it quick, is in their half in a flash, wins the ball to Rashford, 4th goal makes the run from deep into open field and well played ball into Martial to win the penalty.
Ideal world, Fred has the quality of Scholes or Pirlo on the ball but, even without it, he is heck of a player, one you want in big games, where energy and bite are needed in midfield.
