The Chelsea boss was in Brasilia on Wednesday night to watch a Portugal team containing Deco, Jose Bosingwa and Paulo Ferreira get thrashed 6-2 by Brazil.

The trio then faced an arduous journey back to London, and must be doubtful for the fixture.

Yet Scolari, unlike some of his Premier League colleagues, refused to criticise the latest round of international friendlies.

Scolari understands the requirements of national teams, having been in charge of both Portugal and his home nation during his managerial career.

He believes that players must enjoy their time with the national side, even if it means that he is left with little to work with in training.

"It is not a problem for us because we follow the schedule and know the time the players go to the national team," said Scolari.

"It is difficult sometimes because we stay here with five, six or seven players, and it is difficult to do our job.

"But we worked before the players went to the national team. When they arrive back, it is only to check they are not injured and do a little training before putting them on the pitch."

The Blues still have other problems, with both Ashley Cole and Frank Lampard doubtful.

Cole is struggling with a foot problem, and Lampard was forced out of the England squad for the friendly with Germany because of a rib injury.
