In the following years, Martins represented in quick succession PFC Vidima-Rakovski Sevlievo in Bulgaria, Chiapas in Mexico, Venezuela's Caracas F.C.
In early 2012, Martins signed with Syrianska FC from the Swedish Allsvenskan for six months, being released shortly after.
In November of that year he joined Inverness Caledonian Thistle in the Scottish Premier League, but left the following month after only one appearance as an unused substitute.
