I doubt that we'll lose both Dack and Armstrong.
If we do, we'll have about 20 million to play with.
I agree that we need a new, 28 to 30-year-old centre-back, because if Lenihan got injured, we'd just have too little experience.
Keepers are such a gamble. Walton is from a PL club, but his hands just didn't look good enough at times.

Sorry about the lack of "live" responses recently. Doing this on the run.
We have friends in a small town to the north called Whangarei (fanga-ray). Earlier this week, they had 8.7 inches of rain in ten hours, including 1.56 inches in one hour! We've been going there to help clear up, although we couldn't get through, the first day. Unfortunately, more heavy rain is forecast for the next 48 hours, so we may have unexpected guests. Here's the irony! Three weeks ago, Auckland and Northland were still in an official drought - with water restrictions. And this is midwinter!
Whangarei's rain is apparently a 1 in 500-year event.
The trouble is, we've had three of those in New Zealand in the last two years.
So much for Climate Change not happening.
