SMS is a pretty bland stadium and nothing like The Dell to help make opponents feel the pressure. On the contrary, I suspect opposition teams look forward to having a pleasant day out at St Mary's.
Fulham should have been out of sight long before that winning goal. Saints really showed that they're a team of middling Championship players with a losing mentality. Doesn't bode well for next season.
Saints already taking on the role of plucky Championship side. Defend deep and rely on long balls/set pieces. Maybe should have started the season this way.
