The Saints played out a goalless draw with West Brom at The Hawthorns in the Premier League on Saturday afternoon.
Over the course of the 90 minutes, Southampton had 65% of the possession, took 14 shots of which four were on target, and earned five corners.
Hosts West Brom had 35% of the possession, took eight shots of which just one was on target, and earned four corners.
Following the draw, Koeman took to Twitter to express his disappointment at his side’s failure to do much in attack.
Offensively just not good enough. Had a few chances but didn't give away anything. 3rd clean sheet in a row. That's the positive of today!— Ronald Koeman (@RonaldKoeman) September 12, 2015
Southampton are 11th in the Premier League table at the moment with six points from five matches.
The Saints are aiming for a European finish yet again, but they have not made the start they would have wanted.
