Huge disappointment was evident from all after the 3-0 defeat to Middlesbrough and Glenn now has to rally his depleted troops for the visit of Cardiff City in the Worthington Cup on Tuesday.
"It's a difficult game for us after playing like this," said Glenn after the Boro loss.
"The crowd were as frustrated as we were as a team.
"They've been magnificent since I've been here but, rightly so, we deserved to get the bird because we performed that way.
"All season they have been fantastic - and last season.
"Tuesday is going to be real big test for the players and everyone involved. If we win it might get us back on track."
Glenn Hoddle insists the crowd were entitled to give the team 'the bird' on Saturday and says the support has been magnificent since he returned to the club.
