"We have got to approach our task in the right way," the Everton manager said. "I'm not saying Blackburn didn't do so but it happened. The last thing we want is to be leaving here embarrassed, with a lot to do in the second leg."
Royle offered no verdict on where Kenny Dalglish's side went wrong. However, he will warn his players about complacency against the Reykjavik semi- professionals. "We are under no illusions about our task.," he said.
Reykjavik are in their 10th season in European competition but this is the first where they have survived a round, eliminating CS Grevenmacher of Luxembourg at the preliminary stage.
Royle will make no tactical adjustments. "I could have left only one up front as Liverpool did in Russia but I don't think the tie warrants that. Dan [Amokachi] is doing well scoring almost a goal every other game from the end of last season and Anders [Limpar] has been a matchwinner for us," he said.
Everton (4-4-2): Southall; Jackson, Watson, Unsworth, Ablett; Limpar, Parkinson, Ebrell, Hinchcliffe; Amokachi, Rideout. Substitutes: Speare, Holmes, Short, Grant, Barlow.
