Ronald Koeman officially starts work at Saints next week with a potential £100m war chest at his disposal.

The Dutch footballing legend reports for duty at the new look Staplewood training ground on Monday as his squad start preparations for the new Premier League season.

He is facing a major rebuilding job after the club’s transfer business of the last couple of days.

Many of last year’s star players under Mauricio Pochettino have left or are leaving, but it leaves Koeman, pictured, with an enviable transfer budget with which to make his mark.

Saints executive director Les Reed, who is handling all transfer matters at board level, has guaranteed fans that any funds generated by player sales will be reinvested into the squad.

That will be good news for Koeman.

With the sales of Rickie Lambert, Luke Shaw and Adam Lallana generating more than £50m between them – even allowing for Bournemouth’s 25 per cent sell-on clause for Lallana which nets them about £6.25m - he has a strong base to start with.

On top of that Dejan Lovren is also expected to be sold, with figures of up to £15m-£20m being mentioned, which doesn’t seem totally unrealistic when you consider Saints paid £8.5m for him last summer.

The club are thought to have earmarked money for player investment in their budget anyway which can then be added to the figures.

On top of that there is every chance that Dani Osvaldo could be moved on this summer, despite Juventus deciding not to take up their option to sign him.Gaston Ramirez has also been heavily linked with a move back to Italy, all of which could comfortably lead to a £100m pot to spend.

Koeman will need those kind of spending levels though to stabilise things at Saints.

It will be a very different side taking to the pitch at Anfield on the opening day of the season than the one that finished the last campaign.The general consensus was that Saints needed further players anyway to beef up the size of their squad a little as they had been caught out slightly when injuries kicked in.

With a host of players leaving they are set to need even more players.

Key for Koeman will be not only to recruit the right players for the right price, but to try and start spending fairly swiftly.

Though some moves could be held up because of players on World Cup duty, with the squad gathering again he will want the players to have as long as possible to gel in pre-season rather than trying to hit the ground running at the start of the new campaign.
