Bundesliga club Wolfsburg are keeping a close eye on Shinji Kagawa and Kevin de Bruyne.
Kagawa is yet to convince Manchester United manager David Moyes that he is worthy of a regular place in the starting line-up.
The Japanese international remains determined to fight for his place at Old Trafford, but has repeatedly railed against the lack of game time which he feels is undermining his development for club and country.
Belgian international de Bruyne faces a similar struggle to break into Chelsea’s star studded midfield line-up.
Like Kagawa, de Bruyne still hopes to make it in the English Premier League. But Wolfsburg are prepared to offer him a return to Germany, where he played on loan for Werder Bremen last season.
Wolfsburg beat Arsenal to the signing of Luis Gustavo at the beginning of the current campaign, and if the price is right, they are willing to lure Kagawa and de Bruyne from England too.
"We want to do reasonable transfers, just like with Luiz Gustavo" the club’s general manager, Klaus Allofs told Bild.
"That was exceptional in terms of transfer fee and dimension. We want to continue a selective reinforcement of our squad. Not in heave-ho style.”
Regarding the rumours that Wolfsburg want Kagawa and de Bruyne specifically, Allofs added: "If such players are possible, you of course think about them.
“But we should not raise the hopes of our fans. In the end they comment: 'Once again, you failed to sign him'."
