Aaron Cook insists he has no regrets about turning his back on Great Britain as he seeks to make up for his London 2012 snub and book his place at next year's Rio Olympics. Cook, who accepted an offer to become a Moldovan citizen in April, could face former GB rival Lutalo Muhammad in the -80kg semi-finals at the European Games in Baku on Thursday.
