Credit Suisse First Boston is putting up a fight to stop key revenue earners from leaving for Barclays Capital or elsewhere, according to market professionals.

EFinancialNews.com reported on Tuesday during the European session that up to 60 fixed income staff were set to leave CSFB in New York for Barclays Capital. The UK firm is keen to grow its US investment banking franchise this year by more than 100 bankers across the US, Europe and Asia.
