Southampton need a performance to get their fans back on side after a poor run, says Saints boss Nathan Jones.
They travel to Crystal Palace in the third round of the FA Cup, one of five all-Premier League ties this weekend.
"They'll [fans] need to see something they can get behind and that's what we have to do," said Jones.
Southampton, who reached the FA Cup final 20 years ago before losing to Arsenal at the Millennium Stadium, sacked Ralph Hasenhuttl in November and have lost all four league games under Jones.
"The fans won't forget about Wednesday's performance and the only thing that will get them to forget is results," added ex-Luton boss Jones.
