Ronaldo & Ibrahimovic head play-offs

Portugal's Cristiano Ronaldo and Sweden's Zlatan Ibrahimovic take top billing as BBC Sport looks ahead to the European World Cup qualifying play-offs.

One of the two superstars will not be in Brazil in 2014 as their respective countries go head-to-head, beginning with the first leg in Lisbon on Friday.

In the other first-leg ties, Iceland host Croatia, Romania travel to Greece and 1998 World Cup winners France go to Ukraine.
