The Spaniard, speaking ahead of the club’s penultimate game of the season at Brighton this weekend, is under contract at Saints until the end of the season.
Selles revealed his intentions to continue his management career and said he will “absolutely not” stay on at St Mary’s unless he remains the boss.
It had been reported elsewhere that Championship and Spanish clubs are monitoring Selles despite the club’s 11-game winless run ending in relegation.
Speaking on the job he has done,
Ruben Selles said: “If you want to have an all-in mentality it is not only words and that is what I did. It was an all-or-nothing moment and I am always all. I was clear that if I took a step, it was a definite step in this club and a definite step in my career, that is why I did it. I would not change any single second of that decision. Of course, I would change the results we have had and maybe some decisions. If you evaluate your time then there will be things you could do better but I do not change that decision. My agent is working on those things. I get a report every two or three days. There has been some interest, but I will not speak to anyone until I have finished the season with Southampton. As much as the gossip is about other people it is also about me. The gossip is the gossip. I do not know the reality of those things. It is always the same and if you do not want that gossip around you, you have to win more football matches. That is how it works and we know this. I respect the club and everybody knows it. I have a contract until the end of the season and we made it clear we will speak then. If the club makes any decision before that then I would expect to have it communicated to me one way or another before it is made public.”
