Southampton manager Nigel Adkins:
"There were two good goals. I think we dominated the first half and, in the second, we started brightly again before it got a little bit scrappy.
"But a good second goal from do Prado and we saw the game out quite comfortably. I am pleased we kept a clean sheet.
"Our endeavour will be to enhance the squad we have got [in January] but we have an exceptionally good team spirit, which has been demonstrated again today. We have a close-knit group that all want to be successful together."
