Heartbreak City is likely to revert to the Flat for a tilt at the Dubai Gold Cup at Meydan.Tony Martin's Ebor winner came within a head of Melbourne Cup glory in November and was unsurprisingly a hot favourite switched back to hurdles for the valuable Coral.ie Hurdle at Leopardstown earlier this month.While he ultimately came up short, he was not disgraced in finishing a close-up eighth and Martin is happy to let his charge return to the jumping game at some stage.However, the Summerhill handler is currently favouring an appearance on Dubai World Cup night on March 25 for the seven-year-old's next appearance.Martin said: "He's good - there's not a bother on him."We'll see where we are in a week or so, but I'd say Dubai is a fair possibility. That's probably where we'll go."He jumped well and ran a good enough race in Leopardstown, so we could go back over hurdles as well."The owners like their National Hunt racing, so the plan is to mix it."
