The Manchester United forward ended a five-month wait for a goal when he converted a penalty against West Ham last weekend, and the Italian was glad to see his talisman on the scoresheet.
Rooney was on Thursday named in FIFA's technical report for the World Cup as one of England's three "outstanding" players.
"I monitored him during the last game that he played against West Ham," said Capello.
"He's good, he's back and I'm happy because he scored a goal.
"Rooney runs a lot around the pitch, he's free to move where he decides to go. Rooney will on Friday in style."
Capello is closing on finalising his starting XI, with Everton defender Phil Jagielka set to start despite suffering with an ankle injury in recent days.
"The keeper, (Joe) Hart, Rooney, Steve (Gerrard), (Gareth) Barry, (Ashley) Cole, (Glen) Johnson, Jagielka, more or less. I know 10 or 11, with a little doubt about one," Capello confirmed.
