Is there any evidence that the board won't help him? I'm so confused as to where you've got this from. Because I can't think of anything that would lead you to believe the board aren't helping him lol.
Was it the board who didn't sign a single outfield player in 2015 and thought a team that weren't in the title race the season before that would suddenly be good enough to win the title the following season?
Or hold up, maybe the board thought it would be a good idea to strengthen two positions that desperately needed strengthening but would wait until the last day of the transfer window to do it.
Or maybe the board forced Wenger's hand in all of the terrible tactical and personnel decisions Wenger has made over the years.
