"It makes great business sense to have a top rugby player on the trading desk," explains the manager of one of the securities firms discovering the advantages of employing the nation's biggest bruisers.
Some players have qualifications that naturally take them to the City. Brian Moore's legal training and Rob Andrew's background in chartered surveying make them obvious recruits.
However, employers of top rugby players confess they are often paying for something other than professional expertise. They know that many of their clients, especially on the bond and equity desks, are rugby fans.
"You get a better class of person on the bond and equity desks and they tend to be more interested in rugby than soccer and boxing, which tend to remain games for the barrow boys," said one employer of rugby stars.
"Every desk needs a 'face', someone who gives your clients a reason to trade with you," said one desk manager. "You might have a pretty girl or a famous wit, but a big, beefy rugby player is the best."
If their sporting activities mean they are sometimes unable to keep up on day-to-day trading activities, these famous brokers come into their own at meetings with clients, where the talk often turns to sporting matters. The star can often forge valuable business links with enjoyable stories.
"Rugby players tend to be extremely sociable, they can hold their drink without getting silly and they have great anecdotes to tell," said one manager at Liberty, the securities house.
Nor is their ability to get served at busy bars or obtain highly desirable tickets to inter-national matches underestimated by clients and their bosses. Most players get jobs in the bond and repo markets, often trading with the dealers.
One exception to this rule is Simon Halliday, an equity salesman at UBS who started stockbroking in the West Country after he left Oxford University. He argues that the discipline, determination and experience of team work gained can make players well suited for a career in the City. Being a rugby player also helps making contacts.
"Being a national rugby player undoubtedly opens doors, but life can get very frustrating when all your clients want to do is chat about sport and never get around to doing deals," he said.
