Ross made his name when he won the Golden Boot in the Milk Cup in Northern Ireland when he was just 14.Ross had trials with Manchester City and Aston Villa but opted to sign for Millwall F.C .

In December 2011, Gaynor signed for League of Ireland side Sligo Rovers. Despite starting out on the wing he eventually settled into the left back position due to an injury to regular left back Iarfhlaith Davoren. He was an important part of the defence that secured a first league title in 35 years for Rovers while also providing several assists.
He made a good start to the 2013 season again in the left-back position and scored his first league goal for the club in the home win over Derry City. An injury towards the end of the year restricted his appearances but he added an FAI Cup winners' medal to his collection coming on as a sub in the 3-2 win against Drogheda in the final.
