Riemer feels the winger is returning to his best form, having seen him in action for Everton's win at Brighton on the weekend.
He told Viaplay: "Jesper is an exciting player. He has speed, dynamism and unpredictability in his game. This is one of the things that I look for and would like to think that we helped the national team move towards.
"I would say that a Jesper Lindstrøm, whom we remember him when he was at his best level, is entirely a player who will be inside the picture for the Danish national team.
"And I think when I saw him play against Tottenham earlier in January, you saw that some of the old Jesper was left. He has some speed and can create action."
