I disagree . I like Lundstram, he's a tidy player who can tackle and has good distribution. When he plays the Coutts role he looks a decent player. He just doesn't have the energy to replace Fleck, and removing Duffy from the midfield 3 also reduced movement and options for the man on the ball.
Also I thought out of the players coming in (Brooks, Donaldson and Lundstram) Lundstram was the one, who had the best game and looked most comfortable. But it wouldn't be fashionable to criticise the performance of Brooks.
Really don't get why fans don't rate him, especially when you consider how difficult it must be to replace one of the holy trinity.
