For his part, Gerrard has assured McClaren he will be fit and reaffirmed that belief to fans at England's London Colney training complex this morning.
"We will leave it as late as possible but I am very confident Steven will be with us on Saturday," said McClaren.
"We are assessing it day by day. He wants to play, I want him to play, the team does, the fans do and the whole country does.
"It is a big game and we need big players. Steven Gerrard is one of them."
