The Saints head into the encounter in terrific form having beaten Tottenham Hotspur last weekend.
Ronald Koeman has done an incredible job at the club and the team have seemingly stepped up through the gears during the latter stages of the season after a somewhat slow start to the campaign.
Palace have an FA Cup final with Manchester United to look forward to, and as a result they could play a weakened side, prompting Parlour to predict a comfortable home win for the Saints.
“Ronald Koeman has certainly got his players playing well. They don’t want the season to end because they are in great form at the moment. Being at home at in-front of the St. Mary’s crowd, they will be really pleased with how they are developing. I can see this being a comfortable win, 3-1,” Parlour told Betsafe.
Southampton are currently occupying 7th place in the Premier League table, and victory on Sunday could see them climb above both Manchester United and West Ham United if result go their way.
Palace are in 14th spot, and they could rise two place with victory or a defeat could see them drop to 16th, though this game really is meaningless in comparison with their upcoming FA Cup final.
Alan Pardew’s men have enjoyed a great run in the cup, and they will be confident of going all the way.
