The Aston Villa-owned midfielder made the revelation during a ‘Question and Answer’ session on Twitter earlier this week.
The 24-year-old has established himself as a key player for the Reds over the past three or so years and has been in good form in recent months.
In 34 Championship appearances so far this season, Lansbury has scored nine goals and created 65 chances, while having a pass accuracy of 76% and a shot accuracy of 37%.
Another player related to Arsenal who seems to have impressed Gardner is Jack Wilshere.
The England international has struggled with injuries over the years, but the 23-year-old remains an important player for Arsenal.
Gardner has played alongside the Gunners star for England youth sides and has named him as the best player he has ever played with.
During the Q&A session, Gardner also made some interesting revelations about the best player he has played against and his heroes while growing up.
