The Belgium international is out of contract at Premier League club Tottenham at the end of the season.
There is no new deal on the table from Spurs, and it does look likely that the 32-year-old will not be at the North London outfit next season.
The former Ajax star has said that he is going to explore his options and has outlined his plan for the next step in his career.
Sporza quotes Vertonghen as saying: “I’m in a process right now that I have to grab a piece of paper and write down the pros and cons of the options I will have soon.
“I will really have to decide what I want in my career. In three to four years, I will normally return to the place where I will likely settle down.
“I have to start thinking about where I still want to live, what language I want to learn, what culture I still want to live in. And also very importantly: which competitions and prizes I still want to win. I don’t want to regret anything in my career.”
Vertonghen has been on the books of Tottenham since the summer of 2012 when he joined from Dutch giants Ajax.
Over the years, the Belgian has established himself as an important player for Spurs, and has been a key figure in the North London club’s rise.
Tottenham have established themselves as regulars in the Premier League and also reached the final of the Champions League last season.
So far this campaign, the Belgian has made 19 starts and one substitute appearance in the Premier League, and has played thrice in the Champions League for Spurs.
