"Let's not forget Jermaine only played 45 minutes last night and we must not get carried away. But he can look back on a splendid full England debut," said Sir Bobby.
"He showed last night just why we bought him. He is a very fit boy and people who haven't seen him before must have wondered just how he could run about like that.
"JJ was accomplished on the ball throughout the second half but what was particularly pleasing for us was the way he won the ball and came through tackles all the time he was on the field.
"Nottingham Forest fed and bred him and now we are developing him. But to tell the truth we did not expect JJ to become a full international within a year of him joining us but now he can go and improve all the time."
Following JJ’s performance in the second half of the shock defeat by Australia Sven-Goran Eriksson was also full of praise for him, hinting that he may have done enough to keep his place in the squad for the games against Liechtenstein and Turkey.
"Jermaine Jenas did very well. He is a clever footballer and is stronger than he looks," admitted Sven.
