Dušan Tadić felt Southampton should have killed the game off against Hull City, after falling to a 2-1 defeat.
Saints were largely dominant, and had chances to extend their lead following Charlie Austin’s penalty on six minutes.
But after failing to convert their momentum into a more commanding lead, goals in quick succession from Robert Snodgrass and Michael Dawson turned the game on its head.
“We gave two cheap goals and we gave them a chance to go back into the game,” said Tadić.
“It’s really frustrating because we were the much better team and we needed to take the points.
“We know that they were probably going to get some chances and that we needed to be focused.
“I think we should have scored a second goal which would have made it more easy for us.
“In the first-half we played much better but in the second we had some chances where we should kill the game.
“After that they scored two goals from nothing and it’s a different game for them because they got more energy.
“Nobody is happy because we needed those points before the international break.”
