Claude Puel vowed to address the string of defensive errors that contributed to Southampton's defeat to West Ham.
The Saints failed to build on debutant Manolo Gabbiadini's 12th-minute strike as goals from Andy Carroll, Pedro Obiang and Mark Noble sealed a 3-1 victory for the Hammers - their first win at St. Mary's
"It a big disappointment because we started this game really well with a fantastic first goal for Gabbiadini," Puel told Sky Sports.
"We took this goal too easy and we made mistakes. It is important to correct this. It was difficult to finish the first half and after the second half we played attack defence with many opportunities.
"It was a good second half was positive attitude and quality but it was not enough."
Asked if he was worried by the manner in which his side conceded, the Saints boss added: "All of the goals you can correct.
"We lacked concentration about this situation so it's important to correct and find a clean sheet for the next game. That will bring confidence.
"We know we have a good solutions in attack and now with Gabbiadini we can do fantastic results and play.
"But it's important to correct our concentration about free-kicks and defensive mistakes. This is an obligation."
Deadline Day signing Gabbiadini endeared himself to the Southampton faithful with a stunning debut, and Puel insists the Italy international will go on to play a key role for the foreseeable future.
"For a first game we saw a lot of quality," he said. "It was a fantastic first goal and he had a good relationship with his partner with quality.
"He is always available to run in behind the lines. He can also play between the lines. It is very interesting, he can read the play and give assists.
"He is a very good player for and will be very important for the future."
