Ronald Koeman rued a lack of cutting edge as his side crashed out of the UEFA Europa League following a 2-1 aggregate defeat to FC Midtjylland.
Morten Rasmussen scored the only goal of the second leg in Denmark as the Danish champions progressed to the group stage of the competition.
Koeman felt his side tried everything to break down their opponents, but ultimately came up short on a difficult night in Denmark.
“I think we played well. We had a good start in the game and we were the better team,” Koeman told youtube.com/southamptonfc. “We had good chances in the first 15 minutes, but we were maybe not clinical enough.
“One mistake made it 1-0 and then you know it will be more difficult because they will again play like what they did. The team was trying everything in the second half.
“Sometimes you need a little bit of luck. You know if you score out of the chances in the first 15 minutes of the game it will be totally different.
“They got their first chance and it was 1-0. That makes a lot of difference in the game, a difference in belief and the way how we play. We have to take it and we have to learn from it and keep going.”
Koeman was also left frustrated by two decisions over the course of the two legs that he felt changed the outcome entirely. But he congratulated FC Midtjylland on progression to the group stage.
“In my opinion both referees, the referee last week and in Denmark, had a big influence in the final result,” he added. “We scored a normal goal last week and it’s a clear handball on the free-kick of James Ward-Prowse. that makes it more difficult.
“Congratulations to them. They played out of their qualities with good organisation. They had the result what they wanted and we did not.”
