Marko as a RBR consultant is asking the OZ to be a least bit grateful for the achievements of the team, which i don’t see anything wrong.[/quote]
You might be able to read it that way, but to me it came across more as saying that without the amazing car that the team was providing him Webber would be nothing - that it is the car that is winning races not the driver so he should shut up and accept the will of the team. You can spin Marko as being just a consultant, but it is widely reported by multiple sources that he is in effect calling the shots within the team.
This is how James Allen sums up the piece:
After calming words from Red Bull team principal Christian Horner to attempt to end the row over preferential treatment between drivers, Red Bull adviser Helmut Marko has weighed in today, saying that Webber needs to remember that he was no-where before Red Bull gave him a competitive car.
So after Horner tried to calm the situation, Marko was 'weighed in' with critical comments (implying that these comments will not be calming). Marko, with no hint of irony, even claims that the broken wing in Silverstone shows the team does not favour Vettel even though this failure on his car ultimately led to the part being taken from one car to the other.
He says that Mark is having a good season and has improved, but then claims that much of this improvement is actually the car not the driver asking where he was two years ago.
The entire statement reads with a single purpose behind it - to tell Mark to shut up and just accept the way the team treat him. I for one hope that he continues to speak out should the team try and disadvantage him and really hope that for whatever reason there is need for the team to disadvantage Vettel to benefit Webber in Germany. I'm going to enjoy the excuses for not doing so (what are the odds on it being "but it's Seb's home race!").
