Portugal are 1-0 up after the first leg of the World Cup playoff against Sweden but with the return match being held at a stadium dubbed the 'Zlatan Arena' the job is by no means done.
.
Sweden captain Zlatan Ibrahimovic was relatively subdued in the first leg in Lisbon on Friday as a late diving header from Cristiano Ronaldo put Portugal in the driving seat.
.
Ibrahimovic, though, has a penchant for the spectacular at Sweden's home ground and at the age of 32 he will be desperate to take his country through to next year's finals in Brazil.
.
The Paris St Germain forward has scored 10 goals in eight matches since Sweden took up residence at the Friends Arena, including a four-goal haul against England in the opening game there.
.
Three of those goals have come in World Cup qualifiers with two against the Faroe Islands and the other one the winner in their final group game against Austria.
.
Coach Erik Hamren said he wanted an improved performance from his team on Tuesday.
.
"There were too many long balls to Johan (Elmander) and Zlatan on Friday and we didn't have the energy to support the attack," Hamren told reporters. "We've got to have more quality when we win the ball."
.
Ronaldo was also short of his best in Lisbon although he dived in among the flying boots to grab the winner.
