Manchester United's new shirt sponsor TeamViewer suffered a share slump on Friday as concerns over the cost of the sponsorship deal mounted.
It was a change in fortunes for the technology firm, after seeing the valuation of the company rise dramatically during the course of the pandemic.
But Bloomberg report that the stroke dropped as much as 16% on Friday, and they are not the first company to have a negative impact after partnering with Manchester United.
Joel Ewanick, global marketing chief at Chevrolet and the man who agreed a previous shirt partnership for United, was axed within 48 hours of the deal being announced.
