England manager Roy Hodgson says he could end his tenure after Euro 2016 if he does not feel "wanted".
The 67-year-old, who signed a four-year contract in May 2012, stayed in his job despite his side failing to win a game at the 2014 World Cup.
But since then England are unbeaten in eight matches and top their Euro 2016 qualifying group with a 100% record.
"It's tempting to think that one could stay longer, but it has got to be wanted," said Hodgson.
"Sven (Goran Eriksson) and Fabio (Capello) were not that unpopular going into the tournament, but they come out of it and everyone was saying 'oh God, we don't want the next two years (with them)'.
"I don't want that at 68 or 69 years of age."
Football Association chairman Greg Dyke stated in March that he was planning contract talks with Hodgson within the next year.
"I love doing the job," added Hodgson. "I would want that to continue if I was to continue. If I felt that was not to be and my time was being called, I would prefer to move away.
"I don't know if I want to carry on or not."
