The popular 47-year-old was replaced by former Espanyol boss Mauricio Pochettino on Friday and will take charge for Monday night's Premier League clash with Everton at St Mary'sSouthampton fans will express their unhappiness with this week's sacking of manager Nigel Adkins by waving white handkerchiefs during their match against Everton at St Mary's on Monday.
Adkins was replaced by former Espanyol boss Mauricio Pochettino on Friday with the Saints sitting in 15th place in the Premier League following promotion from the Championship.
The 47-year-old was a popular figure on the south coast and had suffered defeat only twice in Southampton's last 12 league fixtures.

"It seems an appropriate way to protest at [chairman] Nicola Cortese's ruthless treatment of Nigel Adkins," Perry McMillan of the Southampton Independent Supporters' Association said.
"As this match is live on TV and will be seen throughout Europe, it's a great opportunity to show how we feel."
Pochettino made 20 appearances for Argentina as a player and was in charge at Espanyol for nearly four years before his sacking in November 2012.
The 40-year-old emerged as a player with Newell's Old Boys in his home country before making nearly 300 league appearances in two spells for Espanyol either side of four years in France with Paris Saint-Germain and Bordeaux.
