Saturday’s 1-0 victory away to Swansea City saw the Saints boss hit the century mark, after just 64 Barclays Premier League games in charge.
Sixteen of those 100 points have come during an unbeaten run in the last six games that has seen them climb to sixth, and Koeman believes they are not only in contention for Europe, but potentially even a top-four place.
Asked about his points tally, the Saints boss said: “It’s not so special. Maybe for a Southampton manager 100 points in one-and-a-half year is special. Maybe yes.
“We are doing well. We had a difficult start to the season. We had a difficult period in December, but we are back again, fighting for a high position in the table, what we want. That’s our ambition – to finish the highest position possible.
“If Leicester can win the title, then we can be fourth or fifth in the league.
“It’s really a tough competition and now we’re one point behind Manchester United. We passed West Ham and it’s all about focus every weekend and, ok, we’re doing well.
“We are looking very comfortable, but we need to keep this. That’s all about training, focus, concentration. We know there are still 12 games to play and 36 points.
"If we get another opportunity to play in Europe we would like to take it."
