Red Bull team principal Christian Horner has slammed suggestions of a conspiracy being mounted against Mark Webber.
The Australian endured one of the toughest weekends of his career in China after suffering issues that wrecked both his qualifying and grand prix.
Coming three weeks after Webber left Malaysia considering his future in light of team-mate Sebastian Vettel ignoring orders to take a win that should have been his, the past two days will have been a bitter pill to swallow.
In qualifying yesterday the team failed to fill Webber's car with fuel due to a fault with the bowser, resulting in him stopping on track during Q2 and a penalty that saw him dumped to the back of the grid.
The team at least made the right call in starting Webber from the pit lane as it allowed them to work overnight on set up for the car.
Come lap 15 Webber was pushing for eighth place, only to run into the Toro Rosso of Jean-Eric Vergne.
The stewards have looked dimly upon the incident as they have punished the 36-year-old with a three-place penalty for next Sunday's race in Bahrain.
The collision forced Webber into the pits for a front wing and tyre change as he had punctured the front left.
However, on Webber's next lap he incurred further woes as he began touring, reaching the hairpin at turn 14 where the left-rear wheel worked loose, finally bringing him to a halt.
Suggested to Horner there is currently a conspiracy against Webber, it provoked an angry response.
"It's complete rubbish, forget conspiracy," said Horner.
"We're all about trying to get two cars to the finish as high as we can.
"Anybody who thinks there is a conspiracy here against either driver does not know what they are looking at."
Pointed out to Horner that Webber was not as vehemently dismissive when such a theory was put to him yesterday, Horner replied: "Mark knows exactly what happened - exactly!
"That's it. There is no conspiracy."
Horner, however, will not know the exact reason why Webber's wheel fell off until after an investigation of the car .
"Until we get the car back we're not too sure," said Horner.
"Mark knows exactly what happened - exactly! That's it. There is no conspiracy," - Christian Horner
"Prior to that he had an incident with Jean-Eric and damaged the front wing and we had a puncture on the left front, so all four wheels were changed and the nose was changed.
"The report from the gun man - who had extra time because it wasn't a hectic stop due to the nose change - was that the right-rear was secure and done up tightly.
"So it's difficult to make any assumptions. Whether it's as a result of the incident, the contact, I don't know.
"Unlikely I would have thought, but until we have all the information it's difficult to draw any conclusions."
Horner has no doubts Webber will bounce back strongly from two tough weekends.
"He was driving very well and was coming back through the field after we had made some big changes overnight to assist him to do that," added Horner.
"The way his strategy was going, it was working very well for him and he was back in the thick of it.
"The contact was unfortunate and then to have to retire the car was even more unfortunate.
"But he'll be fine. He's a tough competitor."
Red Bull were later fined €5,000 by the stewards for the right-rear being incorrectly fitted.
The stewards took into account the fact the team were unaware of the problem when Webber was released from his pit stop.
