Arsene Wenger said he was focused on the match rather than the protest banners trailed behind light aircraft over The Hawthorns on Saturday.
The 67-year-old, who has been in charge of Arsenal since 1996, continues to divide opinion among the club's supporters and the 3-1 defeat to West Brom only worsened Wenger's situation.
Anti-Wenger fans organised a plane to fly over the stadium trailing a banner asking him to leave while another later proclaimed "In Arsene We Trust #RESPECTAW".
The Gunners have offered the Arsenal manager a new two-year deal and Wenger revealed after the game he has made a decision over his future, but has yet to tell anyone at the club.
He has previously stated that he would consider fan opinion before coming to any conclusions.
And when asked about the plane protests over the Midlands during the latest damaging loss, Wenger said: "I watch the game, I do not watch the stands.
"I believe we have to deal with that and you focus on your job, no matter what people think."
