What risk?
Ade isn't even in the squad for games at our most packed fixture schedule despite being reported fit by Poch to the press. Soldado is doing alright at best, he's putting in a shift, he's scored a goal, but we're not in any way shape or form relying on him. He hasn't settled in, he seemingly doesn't fit our system particularly well. Replacing him with someone else who isn't settled really seems like a sideways step at worst. If that new player actually suits our system it could really only be a benefit.
I just don't see what it is we're risking... If we were replacing currently established, functional players that were doing a job for us week in week out, or even players that were currently doing a good job as backups I would see the risk. With Ade there's absolutely no such risk right now as he's seemingly about as close to a start as Ekotto. With Soldado there's very little risk because he's not delivering. We're hoping that he will start to deliver, just like we would with a new striker.
Surely for next season it would be better to have two new strikers coming in now, giving them half a season to settle than replacing one now and one in the summer? The real issue is who is available, or rather, if strikers that will be available to us in the summer are currently unavailable. In that case it might be better to wait. Or if we think we'll get bigger offers for Soldado come the summer than we will now.
