Given that Klopp typically says we're not likely to sign anybody and we go on to sign somebody, I think it's very likely that we will.
At the moment we have 26 over 21 year olds, 18 of them non home grown and we can only register 25 with 17 non home grown. As soon as a couple of players are shifted out (Karius, Shaq? Origi? Phillips? Williams? etc) I think you'll see at least 1, if not 2 players arriving. So many clubs want and need to shift players on and everybody is waiting until the last minute to make their move to get the best price. We don't want to sign anybody until we've cleared room in the squad or we'll be bent over when it comes to shifting Shaqiri for example. If we sign his replacement first then buying clubs will know we cannot register all our players so will have all the negotiatin power. Equally if we're in for somebody like Renato Sanchez (for example as there were some reports earlier) then we know Lille are desperate for the cash so the longer we leave it to more likely they are to drop their demands.
