However, Strachan has described the group - which also includes England, Slovenia and Malta - as "strange" and has suggested that his team could benefit from inconsistent results in Group F
The 59-year-old told reporters: "Slovakia have changed quite dramatically since seeing them twice in the European Championships. Our players know their system has changed a bit and we will have to be on our toes.

Slovakia are currently without a point after losing 1-0 to both England and Slovenia.
