Woodburn - who has 10 Wales caps, scoring twice, including a famous winner against Austria in September 2017 - endured a frustrating loan spell at Sheffield United last season which was ultimately cut short due to a lack of action, before dropping down to League One with Karl Robinson's Oxford United in the current campaign.
Having turned 20 on Tuesday, Woodburn says the experiences of Germany international Gnabry, who is currently excelling at Bayern Munich, give him hope for his future career.
"I have learned so much at Oxford this season, knowing I am able to play 90 minutes and keep fighting for the team. I have taken a lot of kicks and heavy tackles and shown I'm not lightweight.
"I feel like I have had so much experience and yet I am still only young and learning. Watching someone like Serge Gnabry develop is a big help.
"I saw his four goals for Bayern Munich against Tottenham in the Champions League. When he was 20, he couldn't get a game on loan at West Brom.
"He has shown you can push through if you keep working hard and hopefully I can do something like he's done."
