With the squad they have, they genuinely need a good 6-7 players to go straight in to the starting 11, and that's being generous. Even then, those new players have to really hit the ground running.
Of course things could click with the right recruitment and good coaching, but they were so far off Leeds and Burnley last season, I just think it'll be an almighty task for them to stay up, irrespective of them making massive waves in the footballing world.
