Ronald Koeman admitted it was “one of those days" as Southampton were beaten at home by Swansea City on Sunday afternoon.
His side dominated for long periods, but were unable to find a breakthrough against former Saint Garry Monk’s side, before Jonjo Shelvey scored a long-range winner late on.
The home side’s misery was compounded late on with left-back Ryan Bertrand shown a straight red card, as Saints ended the game with ten-men.
Koeman was frustrated his side had not been able to find a goal to reward their dominance, but felt their performance deserved more.
“I was very happy at half-time with how we played in the first 45 minutes,” Koeman told Southampton’s official YouTube channel. “I think we played very good football.
“We had a lot of ball possession and we had some good chances. Maybe we lacked a little bit of sharpness in the box but we played well.
“That’s the problem if you don’t score in the first 45 minutes, you have to keep your organisation and the second half was more difficult.
“There was more space between the lines for them to play but I think the luckiest team won. They came for one point because they didn’t press our defence.
“You need good ball possession, we had that in the first half and we had enough chances to score. Even in the last five minutes we had two good chances to make a draw.
“Maybe it was one of those days that the ball wouldn’t go in. It’s maybe good defending from them but you need to be sharper than we were.”
With Morgan Schneiderlin, Victor Wanyama and Toby Alderwerield nearing full fitness, and Maya Yoshida and Sadio Mané both back involved against the Swans, Koeman is pleased he will have plenty of options for next week’s trip to QPR.
"We have to be calm, keep working at what we are doing, okay, we know it’s difficult, every game is difficult,” he added. “It was a good opportunity and we lost, but next week we will get the next one.
“It’s good news [that the players may be back]. We will have more of a squad, more players and we need everyone in a good way, if not it’s more difficult.”
