Sports Direct chief executive Dave Forsey said: “As we highlighted this time last year, the London Olympics was followed by an excellent ‘back to school’ period.  Therefore to continue to produce these numbers, especially within Sports retail, clearly demonstrates the strength of our business model.

“Since the end of September trading has remained strong and the board is therefore confident of reaching the full-year internal stretch underlying EBITDA target of £310m.”
