Evans arrives in Portugal sharing the championship lead with his part-time Toyota team-mate Sebastien Ogier after claiming an emotional first win for 18 months on Croatia's asphalt roads last month.
The victory resulted in the Welshman leaping up the championship standings that are the closest since 2001, with five drivers covered by 11 points. However, Evans now faces the prospect of cleaning the roads in Portugal, which will reduce his chances of challenging for victory.
