Brazil midfielder Luiz Gustavo insists he wants to play for Wolfsburg for many seasons to come.
Man City's Albert Rusnak hopes to stay at Cambuur until the end of the season but admits the decision is not his.
Manchester United have increased the pressure on Wayne Rooney by using his image to promote next month's friendly with AIK Solna in Stockholm.
On Monday, United manager David Moyes confirmed Rooney was on track to feature in the game after responding well to treatment on the hamstring injury that forced him to fly home from the club's pre-season tour less than 24 hours after his arrival.
Although the player wants to leave United, preferably for Chelsea, the Red Devils have insisted Rooney is not for sale.
And by using Rooney to promote the game in Sweden on August 6, with the word 'Back' superimposed over his image and his shirt number 10 on a picture posted on Twitter, the club appear to be making a significant point.
With two years remaining on his contract, Rooney is hardly in a position not to travel, although there have been suggestions he may opt to force the issue by handing in a transfer request.
There is also the possibility United's stance may soften should they succeed in their pursuit of Barcelona's Cesc Fabregas.
Rooney's fellow striker Robin van Persie did travel to Osaka with his team-mates on Wednesday despite picking up a thigh injury in Tuesday's surprise defeat to J League outfit Yokohama F Marinos.
