Some Arsenal fans may turn up "wanting us to win", says Lincoln defender Luke Waterfall before their FA Cup quarter-final at Emirates Stadium on Saturday.
National League leaders Lincoln are the first non-league team since 1914 to make the last eight of the competition.
They come up against a Gunners side in disarray - they have lost five of their past seven games, including two 5-1 defeats by Bayern Munich, and seen protests against manager Arsene Wenger.
"He is under pressure," said Waterfall.
The Gunners suffered a humiliating 10-2 aggregate loss against Bayern in the Champions League and since the end of January, have also been defeated by Liverpool, Chelsea and Watford.
