Southampton legend Matt Le Tissier is eager for Ronald Koeman to start spending this summer.
Le Tissier also said he hopes they can keep hold of their key players.
"We've seen plenty of examples of where clubs have gone into the Europa League and perhaps their league form has suffered a little bit because of the amount of games they were playing.
"We might lose Morgan Schneiderlin or Nathaniel Clyne, possibly, but if we do we've proven in the past we can go out and replace properly," he told Sky Sports.
