Man Utd fans bombard shirt sponsors with negative reviews in Glazers protest

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.

Fans are now attacking some of the club's global partners in a bid to up the ante on the Glazers with thousands writing negative comments about TeamViewer on review site Trustpilot.

The remote software company, who signed a five-year shirt sponsorship deal with United worth £235million back in March, now has just a 1.1 star overall rating on Trustpilot with 93 per cent of their reviews categorised as 'bad'.

Before the protests against the Glazers, TeamViewer's rating was 4.5.

There has been such an influx of reviews over recent days that Trustpilot has issued an alert on TeamViewer's profile stating that they are a place 'for feedback based on genuine buying and service experiences' and 'reserve the right to remove' any comment that does not reflect that.

Many of the recent one-star reviews have mentioned the company's association with the Glazers.

One comment posted on Wednesday morning read: 'I cannot speak to TeamViewer's product but their company values disgust me. Any company supporting the Glazer ownership of Manchester United will never be used by me.'

Another one added: 'Don't line the pockets of the Glazers.'

Sportsmail has contacted TeamViewer for comment.

A number of United's major sponsors are also being targeted in social media campaigns by fans while a boycott has been announced in an attempt to the pile the pressure on Avram and Joel Glazer.

Fans this week sent a letter to global partners Adidas, Kohler, Cadbury, TAG Heuer, and Team Viewer warning them they will 'boycott your products, seek to tarnish your brands and support your competitors until you terminate your commercial partnerships with the Glazer family'.

The Manchester United Supporters Trust have, meanwhile, again written to the club's chairman Joel Glazer this week urging him to listen to their complaints after Sunday's protests.

The letter read: 'The Fans Forum wrote to you and your senior management team on Friday. We don't know if you saw it, but after the events of yesterday we trust your attention is now fully focussed on the question of what happens next at Manchester United.

'First things first, let's be very clear that no-one wants what happened at Old Trafford yesterday to be a regular event. We are football fans and we want to support our team. We don't want to spend our days off work protesting outside our football ground.

'But what happened was the culmination of 16 years in which your family's ownership of the club has driven us into debt and decline, and we have felt ever more sidelined and ignored.

'After 16 years not one member of the Glazer family has ever had so much as a conversation with us, the club's Supporters Trust. Yesterday, that frustration reached boiling point.

'For the vast majority of the thousands of attendees at the protest they made their voice heard peacefully and respectfully. We support the right of fans to protest lawfully and, although we did not personally witness any such acts, of course we do not condone any acts of violence.

'None of us want this to continue. We all have better things to do. So we need to find a way forward.'

MUST once again put forward a four-point plan for a fundamental restructuring of the club.

As well as calling for the Glazers to co-operate with a fan-led government review into football following the European Super League debacle, the letter urged them to put in place a share scheme that is accessible to all investors meaning the owners' stake could be 'reduced to a minority or indeed be bought out altogether'.

The letter also called for the owners to consult with season-ticket holders over any significant changes at the club and appoint independent directors to the board.

It concluded: 'We request a response to this four-point plan, in public and in writing by Friday. This is the only way to move this issue on. We strongly suggest you take it.'
