Leeds United boss Marcelo Bielsa says there'll be no underestimating Southampton.
Saints go into the game winless on Saturday.
Bielsa said: "When you describe a game in the Premier League, there is always a level of difficulty in all of them.
"There are some games that are a little bit more than difficult but it is impossible to say before the game.
"What we are absolutely sure of is that Southampton will be a very difficult opponent to overcome. You can interpret that as a formal declaration or you can evaluate why type of opponent Southampton are.
"For example against Manchester City, you see how they play. Apart from that, it is very difficult for someone to think we can interpret a game as accessible before having played it."
