Danny Higginbotham doesn't believe that Southampton's back-up players are good enough to help them push for a top-four finish in the Premier League this season.
The retired defender, who made 94 appearances for the Saints between 2003-06, credited some of the club's 'outstanding players' but has concerns about the quality of their second string should they need to be used.
He told talkSPORT: "I don't think top four.
"At Southampton they have got some outstanding players, but if any of those two or three players go off the boil and things don't go according to plan, the players to replace them in my opinion aren't good enough to sustain them in the top four."
Higginbotham went on to add that due to the poor results they have picked up against bigger sides, a top-six finish and Europa League qualification would be a much more realistic target for Ronald Koeman's side.
"Top six is a possibility but, no, I don't think top four. They've had a fantastic start to the season there's no question of that but you look at the results they've had against the top, they seem to lose them, so I don't think there's any chance of top four for them."
The Manchester United academy graduate was speaking after the Saints lost their third consecutive match against United last night.
Defeats against Arsenal, Manchester City and United have dropped them to fifth place in the league, which should still be regarded as a great achievement considering the expectations many had for them this season.
Saints supporters will be hoping their team continue pushing for their highest ever top-flight finish by breaking their losing streak away at Burnley this Saturday.
