Werder Bremen have also been linked with the man signed by Alex McLeish and Courant confirmed: "Marseille is a place to think about for Thomas and I know Eric Gerets very well.
"We've had some contact with them over recent weeks. They are a big club who were in the Champions League this season, so that could be an interesting option.
"There could be something in Germany, as well, with Hannover having tried this time last year to sign him. Some of the Bundesliga style of play may suit him. Thomas is only 26, so he should be in the best years of his career."
