Southall told evertonfc.com: "I think you had Richard Wright in Paul Gerrard. I didn't quite see the sense in bringing Richard in because I thought Paul was as good, if not better than Richard.
"Paul had that experience of playing in the Premier League but I think Richard probably got found out at that level. Again he'd been at Ipswich where you could have a couple of worldies and then nothing for six months.
"Richard is a really talented goalkeeper but he couldn't really make that step up to world class. It's a shame."
Wright is currently No2 at West Ham United.
