Oxlade-Chamberlain was sent a number of messages from Arsenal supporters on social media pleading with him to help stop rivals Spurs from becoming the first north London side to claim the European Cup.
"It was massive for us at Liverpool but once a Gooner, always a Gooner.
"I had a personal feeling in that game that we needed to get it done for all the people I left at Arsenal.
"I know they were all willing us on to win that one. I'm happy that we could do it."
