Yes, the number of entrants is massive too. Most UK DFS sites have at best few hundred players playing each game week regularly.
Salary pricing is sharp. Have to look hard for bargain basement players who can get good returns. Khazri for Sunderland looks from the new players most suited to DK game.
Firmino looks a good player for DK game too. But most attacking players will scrape on 1 to 3 points, so best to make a list of players with all-round game.
I am laughing about the free UK fish money, the sharks will feast till they full Ronaldo. Take it easy and pace yourself. Even max the biggest shark plays soccer DFS. Oh dear!
