Luis Aragones's side proved they were vulnerable to Northern Ireland's dead-ball delivery and direct approach in Belfast last month when they were surprisingly beaten 3-2.

"Against Northern Ireland we suffered from their set-pieces. Many games are decided from these types of plays so obviously we have been spending time practising them," Spain defender Juanito told a news conference on Thursday.

"Sweden are a tall team and like our previous opponents are very direct. They have good wingers and good finishers."

After conceding three goals in Belfast, Aragones looks set to re-model his defence, drafting in Real Betis centre back Juanito in place of Pablo Ibanez, and Deportivo Coruna's Joan Capdevila for Antonio Lopez at left back.

He has also hinted that he will change the formation to give the side more defensive solidity, and that they will look to play more on the break.

Group F leaders Sweden are without leading striker Zlatan Ibrahimovic, who has refused to play after clashing with coach Lars Lagerback, but Spain are refusing to drop their guard.

"Ibrahimovic's absence is good for us but we must be careful," said Valencia forward Miguel Angel Angulo, who is set to start on the right side of midfield.

"His replacement up front will be really keen to impress his coach and thank him for being given a chance."

Spain are joint second in the group with three points from two games, three behind unbeaten leaders Sweden.
