West Ham say they are already in discussions with companies to find a new sponsor for next season.
“West Ham United has enjoyed a good working relationship with Alpari (UK) Limited since 2011 and??is therefore saddened by today’s news that it has entered into insolvency,” read a statement on the club’s official website.
“The club would like to offer its sympathies to any Alpari staff affected by the announcement, particularly those that have worked closely with us over the past few years.
“The board would like to reassure supporters that Alpari (UK) Limited’s situation will have no impact on West Ham United.
“The club remains in a strong financial position and just last month published accounts showing record revenues and a group profit of ??10.3m before tax.
“The club has received huge interest and is already in advanced discussions with potential new shirt sponsors for next year.”
