Hong Kong billionaire Carson Yeung bought a 29.9 per cent stake in the quoted Premiership club.
Holborn was brought in through its association with Keith Harris, the executive chairman of Seymour Pierce Investment Bank.
Yeung used Seymour Pierce for his £14.7m approach for a stake in the Blues through his Hong Kong-based company Grandtop International Holdings.
His stake is seen by many as a prelude to a full takeover and sources close to the club have said its owners have been looking for a feasible buyer for some time.
Holborn chairman David Bick heads the account. Should a further offer be made, Holborn will be able to rely on a history of handling foreign takeovers, including Aston Villa’s last year.
The appetite for foreign takeovers has been whetted by furious PR efforts surrounding the recent Villa, Liverpool and West Ham deals – all of which were received largely positively by stakeholders.
Holborn is also working on deposed Thai Prime Minister Thaksin Shinawatra’s takeover of Manchester City – a deal that also involves Keith Harris (PRWeek, 4 May).
Shinawatra’s proposed takeover, which is apparently nearing completion, is being viewed in the Far Eastern press as a PR manoeuvre intended to raise Shinawatra’s profile.
According to reports, Harris has been central to the potential hiring of former England manager Sven Goran Eriksson as manager.
