Eriksson will wait until Thursday before making his decision on Rooney

Eriksson said Rooney will not start the match, but had yet to decide whether the 20-year-old will play some part.

Meanwhile, Rooney's Manchester United team-mate Gary Neville looks set to be ruled out of the Group B game.

Eriksson said the right-back was very doubtful after pulling out of a training session with a calf strain.

Neville is to undergo a scan, with Owen Hargreaves or Jamie Carragher set to step in if he does not recover in time.

Rooney has not played since breaking his foot in a Premiership match against Chelsea on 29 April.

"For me Rooney is match fit but let me sleep on it. I will decide tomorrow morning," said Eriksson.

"Almost for sure (he is) not starting the match, I don't think he has 90 minutes in him yet."

Eriksson denied he had a row with FA chief executive Brian Barwick over the striker's comeback.

Barwick was reported to be opposed to his return because the FA's insurance policy might not provide sufficient protection if the player suffered a secondary injury in Nuremberg.

"It has been reported that Brian and I had a row about it which is completely a lie. We have discussed it all, it is not a dispute, no," said Eriksson.

"We will talk about it after the game, it is not fair to do it in front of the team."

Neville withdrew from the training session with a calf strain

Neville withdrew from training at the Franken-Stadion just 15 minutes into the final session.

The 31-year-old defender spent a couple of minutes on the sidelines before heading down the players' tunnel with England physio Gary Lewin.

In contrast, Rooney looked sharp and appeared to be enjoying himself in sweltering conditions.

Eriksson refused to confirm whether Michael Owen, who was taken off after only 55 minutes of England's 1-0 opening win over Paraguay, would start up front alongside Peter Crouch.

England struggled in the Frankfurt heat on Saturday, and the players were greeted with a temperature approaching 30C as they arrived in Nuremberg.

Weather forecasts suggest humid conditions for their second group match, despite it kicking off in the early evening (1700 BST, 1800 local time).

Leading German weather forecaster Joerg Kachelmann said: "It's probably going to be hot for England after all."

Fifa has promised it will ensure players have access to water during stoppages in play.

Earlier, Neville had said the heat should not be used as an excuse for Saturday's laboured display, and the team needed to improve their passing and movement.
