Vieirinha is a decent player..no world beater, but he constantly increased his performances and is now a relatively good and reliable player. He would be good as a squad player, but his contract is running out upcoming summer and he is obviously trying to use that situation to his advantage. Wolfsburg offered around 3.5m€, but Schalke is rumoured to be in pole position offering his 4.5m€..gross of course. His advantage is, that he is also a decent RB and so he could be useful there for Schalke as BU for Uchida and as additional option for the RW. Heldt also likes to overpay for wages a little for Bosmans or players having clauses..Stindl from Hannover (3m clause) prob next.
I guarantee u that Bayern want De Bruyne..for sure they want him as soon as possible. What makes him interesting r not his skills to play on the wing though..he is simply not fast enough and no Ribery or Robben at all. Bayern obviously think that even Reus isnt perfectly suited to their system (I agree), so De Bruyne makes even less sense. No they want him, cos he would be ideal for their midfield. He is very complete and energetic with a lot of drive and good technique. That he can ALSO play on the wings and being useful there makes him interesting so that he can shift positions during the play..his versatility..more in the mood of Thiago than Ribery, but of course with his own attributes.
I agree the very good relationships with VW and VfL make him a very possible candidate, but Bayern for sure wont get him upcoming summer and the chances in 2016 r not very high too..2017 would be the most realistic prediction, as he obviously has no buyout clause.
The not very smart comment about Germany being just a short term solution while being at Bremen on loan is history..he was young and didnt know better..now he does, cos the style of Bundesliga suits him like a glove.
