Manchester United supporters have bombarded shirt sponsors TeamViewer with negative reviews on Trustpilot and launched a boycott campaign against the club's global partners in protest against the Glazer family.
Fans desperately want to drive out their American owners and are now rallying against the club's major sponsors after last weekend's protests at Old Trafford caused Sunday's match with Liverpool to be postponed.
The American billionaires have never been popular with fans but are now under immense pressure to step down with fans threatening to continue protesting until they resign after being left outraged by their involvement in the botched plans for a breakaway European Super League.
