Sweden coach Lars Lagerback insists his squad are full of confidence ahead of their crucial final Group B encounter with England on Tuesday - but he is wary of the threat of Wayne Rooney.

Freddie Ljungberg's late winner against Paraguay on Thursday ensured the Swedes only need a point to join England in the last 16 and a win against Sven-Goran Eriksson's men would see them go through as group winners.

Despite winning both of their group games against Paraguay and Trinidad and Tobago, England have not been at their best in Germany so far, but Lagerback is expecting a tough test, especially with Rooney available for selection.

"Our confidence is high. It's difficult to say what other teams will do, but I guess England will try hard to win the game," Lagerback said.

"It will be a hard match. For us one point is enough, but we firstly have to control the match.

"The quick return of Wayne Rooney is good for him and the World Cup, because we all want to see the best players, but for us it is a little bit difficult."

The Swedish coach is giving nothing away with regards to his team selection, insisting he has yet to decide his line-up for the crunch clash in Cologne.

"I don't have a starting XI in my head, I'm not sure about it," he said.

One player who looks set to be out of contention for the Swedes though is striker Zlatan Ibrahimovic.

The Juventus forward damaged his groin just before kick-off in Thursday's match against Paraguay and although the 24-year-old started the game, he only lasted until half-time before being replaced.

Sweden team doctor Magnus Forssblad revealed on Saturday that Ibrahimovic was on the mend but conceded that he was unlikely to make the England clash.

"It's a minor muscle injury in his left groin. He feels much better today and we are doing all we can to have him fit for the next match," Forssblad said.

"But probably, he will not be available. Whether he can play in the next round, it is difficult to say."

Lagerback, whose side will play either Germany or Ecuador in the second round if they manage to take at least a point against England, added: "Zlatan is a very important player for us, but that's football."
