West Ham United boss Slaven Bilic feels his side will respond to their opening day defeat to Manchester United when they visit St Mary’s.
The Hammers fell to a 4-0 defeat at Old Trafford, with a number of key players missing through injury.
And Bilic believes that they are in good shape heading into this weekend’s game on the South Coast.
“After Sunday’s game, the players were gutted. I was gutted. But when we came back into training, the focus immediately turned to Saturday and how we needed to react,” he said.
"I believe in my players. They showed on many occasions last season a good reaction when it was needed during tough times, and I have confidence that we will see that reaction again on Saturday.
"They have shown me the right attitude in training this week, and have worked extremely hard to prepare for this game.”
In his weekly column for whufc.com, Bilic also reserved praise for Saints after watching the opening day draw with Swansea.
“Southampton are a good side. They have a new manager in Mauricio Pellegrino, but despite a few changes of manager in recent years, they keep the same model and the same system,” he said.
“For me, they play good football. I heard a few people say last year that they were boring, but I don’t agree with that. They have some dangerous attacking players.
“They didn’t score against Swansea last week but they played well and should have won the game. They are a good team, and they were a good team last season, but we beat them 3-1 at their place and we have to find that level of performance again this weekend.”
