Radhi Jaïdi was left frustrated by a host of first-half errors as Southampton's youngsters fell to a 3-1 defeat against visiting Blackburn on Monday evening.
Saints had conceded all three inside the opening half hour, a particularly infuriating detail for Jaïdi, who was disappointed by a number of individual mistakes that led to goals.
The second half was much improved for the home side, as Callum Slattery's penalty reduced arrears, but the damage had been done in the first 45 minutes, and Jaïdi knows that Saints must do better in order to pick up points in this league.
"Not good enough," the former defender began. "We gave away the game in the first half. It was a poor start with a lot of individual mistakes.
"Collective mistakes as well. This is a bit strange for some of the boys.
"The second half was slightly better, as a group. In this competition you have to compete, you have to work hard, you have to show the will and desire. We didn't do that.
"We need to talk seriously about it. Starting tomorrow, we need to show a bit of character against these types of teams.
"We have some young boys in this team, and they've been doing okay - with the ball. But football isn't just about possession.
"Teams come here to challenge, to tackle, to head it and you've got to stand up to that. The ugly side of the game, you have to do it.
"Leicester is an opportunity for us to put this behind us, and move forward."
