Portugal and Iceland have met twice before, during qualification for Euro 2012. Portugal won both encounters and much of the same is expected in St-Etienne.
The script seemed to be going to plan with Portugal completely dominating in the first-half.
Just after the half-hour, Andre Gomes was given too much time on the right and used it to cross in low for Nani to tuck in.
Half-time: Portugal 1 - Iceland 0
Just five minutes into the second-half, Johann Berg Gudmundsson's deep cross allowed Birkir Bjarnason to nip in and score Iceland's first goal at a major tournament.
Iceland's Hannes Halldorsson was made to work for the next forty minutes but he kept the ball out of the net and Iceland held on to a point.
Group F in St-Etienne.
