"We haven't been very successful in the cups in recent times and I said I'd like a cup run this season, well, we've got one. The players have been magnificent throughout and this was an unbelievably disciplined performance.
"It is difficult singling anyone out because they all were excellent. They had to be because Southampton can play and they have players in areas where it is difficult to mark.
"But we stuck at it and I was pleased with some of the quality we displayed at times. We mixed it up and caused them problems. Southampton pulled back into it with an outstanding goal from Stern John but we kept our heads and extended the lead and saw it out", a delighted Robbo added.
"It is important to remain grounded though as we are still on minus points in the league and up against a very difficult Dagenham team on Saturday."
