Leyton Orient boss Russell Slade claims some fans should have stayed at home after criticising their treatment of goalkeeper Shwan Jalal during their 3-1 home defeat to Bristol City.
The O's crashed to their third consecutive defeat as their promotion hopes suffered a major setback.
Jalal, on loan from Bournemouth, struggled throughout the match and was to blame for the Robins' third goal. But Slade hit out at supporters for their sarcastic applause and negativity towards the keeper.
Slade said: "I have to say tonight I thought the fans that were cheering when he caught the ball on several occasions I think that's shocking. I wouldn't wish that on any professional player. I don't think anybody deserves that.
"If that's their way of protesting or not getting behind the team, then to be honest I'd rather they stayed at home."
Orient have suffered a series of goalkeeper setbacks with Jamie Jones injured and recent signing Ben Alnwick unavailable for medical reasons. Hull keeper Eldin Jakupovic made a huge impression in his short time, before being recalled by the Premier League side, and Slade could attempt to bring him back to Brisbane Road on loan.
The manager said: "It's safe to say I want to help the group as much as I possibly can. If that means we can do something in the loan market and it's feasible then I will do that to try and help."
The O's have slipped down to third in League 1 after their worst spell of the season but Slade still has faith in his squad to get back on track quickly.
He said: "I trust the group of players that we've got. They need a little bit of help at the minute. We're having our first little wobble of the season for one reason or another. I don't think the keeper situation has helped us in that we've had to change keepers on several occasions.
"But they're a good group. W'll come through it but we need to come through it sooner rather than later."
