Werder Bremen midfielder Diego has received offers to leave the Bundesliga club at the end of the season.
Serie A side Juventus have already agreed terms with the 24-year-old, according to reports in Italy, while the player claims other clubs have also made contact.
But it is not yet certain that he will leave Bremen in the summer and talks at the end of the season will determine his future.
"There are three possibilities," he told Sport Bild magazine. "When we sit down and decide on my future after the season, I could either leave, stay or even sign a new contract extension here.
"I have fulfilled all of my expectations in Bremen so far and am very happy with Werder. I have a contract until 2011 and I would never break my contract."
Diego's deal with Werder expires in 2011, but the prospect of not playing in Europe next season may make it hard for the Bundesliga giants to convince him to stay.
Juve and Inter Milan, another club reportedly in the hunt, are both practically certain of a place in the Champions League next season and that could help them in attracting the Brazilian playmaker.
Furthermore, the lack of the income generated by European football could tighten Bremen's budget and the sale of Diego, when he would still command a considerable transfer fee, would enable them to bridge that financial void and still afford to find a replacement.
