This would mean we would need to sign 1 Goalkeeper, 1 Fullback, 2 Centrebacks, 1 Central Midfielder, 1 Winger, 1 Attacking Midfielder (a 10), and 2 Strikers to make a squad of 25

Don't know who these additional players would be but I'm sure our richer ownership should be able to facilitate such transfers
