And he was caught up in a storm over an alleged obscene gesture to a German fan at the weekend.
Eastwood said: "I will definitely be targeting Lehmann again.
"Germany always seem to play him whether he is playing for Arsenal or not.
"Hopefully he will be in goal and hopefully I can get a few shots off and maybe nick one. I'd love to stick one past him."
Lehmann insists he did not gesture at anyone and is set for showdown talks with coach Joachim Loew over his Euro 2008 spot.
Loew, who wants the keeper to quit the Emirates or win back his place from Manuel Almunia, said: "It isn't so simple to start someone who hasn't played for eight or nine months."
