I can see the evrybodys point.
Whether Upson is good or not is down to opinion. Moyes might not rate him, or may not even be able to attract him. There are always ifs and buts.
Another CB wouldn't do any harm though.
Distin is ageing, as is Neville, and Heitinga isn't a cert to stay. Yobo is surplus either by choice or by Moyes' decision, and Duffy has little experience. Jags was pretty poor last season, and if Arsenal offered the right fee would be gone.
There's no such thing as a free though. Signing on fees and wages are always expensive. No matter which way you look at it, even 20k a week is a million per year, and a million more than we can afford. Unless someone left, it's an extra mouth to feed.
