Southampton manager Mauricio Pellegrino apologised to Saints fans after his side's poor display during their 3-0 defeat away to Newcastle United on Saturday.
A brace from Kenedy and Matt Ritchie strike completed a comfortable win for the hosts, although they were helped by a lacklustre Southampton who failed to compete for the majority of the game, which was something that irked Pellegrino after the game.
Speaking post-match to Sky Sports, he said: "
"We made this mistake and paid the price for the rest of the game. At this level you cannot start in this way because we missed an amazing chance to try to improve.
"When you lose everything looks worse than it is. It looks very difficult now but in a week we've got another game in the FA Cup and we have to show our best to change our spirit on the pitch.
"The attitude is everything. Without the right attitude, it's difficult to compete."
