Arsenal boss Arsene Wenger is remaining cautious about using Eduardo in the FA Cup replay with Cardiff.
Eduardo made a successful return to competitive action in midweek when he came off the bench to set up Croatia's winner in the 2-1 victory over Romania.
The striker, who has been out for almost a year after his horrific leg break against Birmingham last February, is pushing for a return to the Arsenal side.
Eduardo was among the Gunners' unused substitutes against Tottenham at White Hart Lane last week and he will be hoping to be involved against Cardiff in Monday's re-arranged clash.
However, Wenger is cautious about rushing Eduardo's progress.
"He is back and ready to go," Wenger told the club's offical website.
"I don't know [about Cardiff]. I don't want to promise anything. I want the freedom to pick the team I want to pick."
Eduardo, meanwhile, was happy enough with his run-out for Croatia, in which he set up the winning goal for Niko Kranjcar.
He said: "I feel good and I proved that I can play again.
"All my team-mates asked me if I was scared, but I'm happy not to fear anything on the pitch and I'm ready to play.
"When I came on, I must confess that I felt tension in my stomach, but it disappeared when I made my first touch.
"The most important thing is that I'm back, but I still have work to do to be the old Eduardo."
