Arsenal staff are fearing job losses – after the side won the Premier League title for the first time in 22 years.

Daily Mail Sport understands that US consultants BCG have been carrying out a review at the champions for the last three months.

It is believed that BCG managing director Jean-Paul Petranca is leading the review, which some claim has created a split within the offices of the club despite a stunning season in north London in which the Gunners also reached the Champions League final.

Arsenal insiders insist that BCG are there to help the club grow the business, capitalise on their success and ensure a sustained period of high performance.

However, sources have disclosed that many staff members believe job cuts are inevitable and that there is a perception – and an anger – that the football side of the business will not be impacted.

Petranca, who has been reporting to chief executive Richard Garlick, has ‘more than 20 years' experience advising senior leaders in the UK and internationally on strategy, transformation, and organizational performance’ according to BCG’s website.

Arsenal have refused to comment but it is thought that making efficiencies is part of Petranca’s remit.

There is thought to be a particular nervousness within the commercial department, with some staff struggling to see the logic behind any cuts, should they take place.

In the summer, that side of the business lost its boss, Juliet Slot, who departed after almost five years with the club which saw record-breaking revenues.

There is a view that any restructuring in that area would be incredibly short-sighted given Arsenal, like many others, rely on driving income to ensure they comply with the Premier League and UEFA’s spending rules. The emphasis, many believe, should be on servicing relationships with existing partners, while searching for new sponsorships.

One member of staff, speaking anonymously, explained: ‘Obviously everyone was delighted at the success of the team last year. But it has not gone unnoticed that the football department, which has extended recently, appears immune to any changes. 

'It doesn’t feel right that, given the amount of money spent there, normal people with bills and mortgages to pay feel under threat. 

'You would think that it’s a great place to be at the moment but that’s just not the case. There’s also an anger that, should there be cuts, they will be made by someone from outside the business rather than your own boss.’
