"Yeah, of course. Podolski is a massive name. I've been watching him for a number of years," Oxlade-Chamberlain said when asked by Sky Sports News if he was impressed by the signings.
"He's got 100 caps for Germany which is a massive achievement in itself.
"Giroud is a very good striker as well. He scores goals and brings quality to the side and that's what we need.
"You've always got to bring in new players and they're fantastic signings.
"I've met them and they're both really good lads so I think we'll get on really well this year and they'll be really good to play with."
