Wijnaldum is currently inside the final 18 months of his Reds contract.
"I sometimes watch Sparta and then I think: Well, it would be nice if I played there in my last years.
"In the Netherlands I have played at three clubs and I have had a very good feeling about all three. But you can only choose one."
However, Wijnaldum does not want to create false hope.
"I also learn from other players. Ruud van Nistelrooy once made the promise to return (with PSV), but at a later age he didn't want that anymore.
"What I am experiencing now is unique. You want to play at the highest level and win prizes. Just like Clarence Seedorf. My dream is to stay fit for as long as I can. Just like him, Zlatan Ibrahimovic or Cristiano Ronaldo, playing at a high level."
