But the highly-rated Argentine coach played down reports this week linking him with Tottenham, although he did stress he hopes to manage in the Premier League for a long time.
Asked about the Spurs reports, Pochettino said: "In football I am very much accustomed to living with these rumours.
"I have been living with and hearing these rumours all my life, firstly as a player, and then as a manager. I am just calm. I am not reacting to these rumours.
"I am fully focused on the job ahead. My job ahead is these last five games of the season with Southampton to try and get as many points as we can.
"Tottenham still have a manager, I still have one more year on my contract. I don't talk about rumours and I'm focused on this job.
"I said back in January that, at the end of the season, I will be speaking to the club. The possibilities are open."
Real Madrid, Marseille and Monaco are also believed to be admirers of Pochettino but, asked if his long-term future lay in the Premier League, he said: "Yes, yes, yes.
"I would like to be in the Premier League, it is the best league in the world, and I'd like to be here as long as I can."
Pochettino has also revealed that Jay Rodriguez is coping well with the disappointment of suffering a serious knee injury at Manchester City last weekend.
The England international has been ruled out for six months and will miss the World Cup but his manager said: "I am certain that he will become reinforced out of this situation, he is going to return stronger.
"No player likes to go through the situation he is about to go through, but I am positive he is going to return and going to return reinforced and reinvigorated from this difficult situation he is in.
"You could see the initial impact on his, as well as the team's faces.
"It was a heavy blow to take and it had a massive impact on the team but, in terms of his recovery, Jay has been coming to the training ground more or less 9.00am to 4.00pm or 5.00pm every day.
"He has already started his treatment, his recovery. He is mentally strong, which is really important for him, and of course he has the 100 per cent support of the staff.
"We're all supporting him and it is clear he is in very high spirits despite the injury he sustained."
