Southampton have shown their strength in depth and quality of their youngsters with the sale of Jack Cork to Swansea City.
The 25-year-old left to join the Welsh side after rejecting the offer of a new contract from the Saints.
Plenty of options
Although the sale of Cork comes at a time when Southampton have injuries in his position, manager Koeman would not have sanctioned a deal if he was not confident in the options he has available.
First and foremost on that list would be Harrison Reed who has featured prominently in the last couple of weeks. His improvement coincided with Cork's injury and the latter struggled to regain his place when he returned.
The Dutch manager has also called on Jake Hesketh on occasion and it seems that he has also done enough to convince his manager to keep him around the first team squad.

The South coast outfit have also been linked with Tonny Vilhena in recent days, with the Saints boss confirming his interest in the player he says is unhappy in Holland.
They have also been showing an interest in Benfica's Serbian front man Filip Djuricic, who would be a useful addition out wide or in the free role.
Either of those players can take a more advanced position in midfield which would allow Steven Davis to shuffle into the central position if needed.
Strong in midfield
Koeman confirmed that Cork would not have been in his first choice midfield three and that has led to the player seeking pastures new.
Although Cork would be a good player for the majority of sides in the Premier League, the Saints are aiming to join the elite and unfortunately that leaves no room for sentiment.
With the players at his disposal, Koeman could not offer Cork the playing time he wanted and they came to an amicable solution.
Transfer window dealings
Should the Saints make the step up in Europe next season, Cork would probably have been pushed even further down the pecking order, so making a move now works for all parties.
The move for Cork means the Saints can now attempt to tie up deals for Vilhena and Djuricic in the remaining hours of the transfer window as they look to finish in the top four this season.
