Brazil midfielder Luiz Gustavo insists he wants to play for Wolfsburg for many seasons to come.
Reading are one of several English clubs in talks with Russian striker Pavel Pogrebnyak, according to his agent.
The 28-year-old spend the second half of last season on loan at Fulham from German side Stuttgart, netting six goals in 12 appearances.
Pogrebnyak is out of contract this summer, and it has been reported newly-promoted Reading are poised to sign him up on a four-year deal worth around £65,000-a-week after the striker turned down an offer from the Cottagers.
However, Pogrebnyak's representative Oleg Artemov maintains nothing is yet decided.
Speaking to Russian news agency R-Sport, Artemov said: "We are not just holding talks with Reading. There are other English clubs.
"I think that a final decision will be taken in a week's time."
Pogrebnyak made just one appearance at Euro 2012, coming on as a substitute against Greece as Russia lost their final group game and went out of the competition.
Backed by new Russian owner Anton Zingarevich, Royals boss Brian McDermott has been keen to bolster his squad on the return to the Barclays Premier League, signing former Nottingham Forest winger Garath McCleary on a free contract.
Watford defender Adrian Mariappa, Forest's Chris Gunter, Hull City's Robert Koren and Huddersfield striker Jordan Rhodes have also been linked with the Berkshire club.
