Andre Schurrle and Julian Draxler have remained coy on their futures at Wolfsburg after a disappointing 2015-16 campaign.
Wolfsburg finished runners-up in the Bundesliga last season as well as winning the DFB Pokal but, with star man Kevin De Bruyne leaving for Manchester City last summer, they had to settle for eighth place this time around.
The club's sporting director, Klaus Allofs, has said there could be an overhaul of the squad ahead of the new season, and there have been suggestions that former Chelsea forward Schurrle could move on, with Liverpool and Tottenham linked.
Schurrle has enjoyed a significant upturn in form since the turn of the year, scoring all nine of his goals in the second half of the season, including a brace in a 3-1 win over Stuttgart on Saturday.
When asked about his future by Bild, the 25-year-old Germany international said: "I think that it's too early right now. I will now prepare for the Euros. I will try to play a very good tournament with Germany and give it my all.
"We'll see about the rest after that, but it should not sound like I am already in the starting blocks here. There is nothing right now."
Fellow Germany international Draxler was brought in from Schalke following De Bruyne's exit, but he was recently linked with a return to the Veltins-Arena.
He has already dismissed those rumours but the 22-year-old, who made his return to action on Saturday after over a month out injured, said he has given little thought to his future.
"My focus was on the comeback and now it's on the Euros," said Draxler, who set up one of Schurrle's goals against Stuttgart. "Everything else is not an issue."
Speaking to Sky on Saturday, coach Dieter Hecking was asked whether Draxler would still be a Wolfsburg player next season. "I'd like to think that," he replied.
Wolfsburg have already seen defender Naldo opt for a move to Schalke this summer, with the 33-year-old Brazilian able to leave on a free transfer because of the club's failure to qualify for Europe.
There are also doubts over left-back Ricardo Rodriguez, who has been linked with Real Madrid, and holding midfielder Luiz Gustavo, who has said he is open to a move to China. Both players have release clauses in their contracts.
On Sunday, Die Wolfe announced the signing of 17-year-old Croatian forward Josip Brekalo from Dinamo Zagreb, who is reported to have cost around €7 million.

Wolfsburg have also heavily been linked with versatile Cologne midfielder Yannick Gerhardt.
Kicker reports that the two clubs are negotiating a transfer fee, which is likely to be in the region of €13m.
