Peterborough United boss Darren Ferguson has hit out at supporters who criticised goalkeeper Joe Lewis in Friday's 3-3 draw with Bournemouth.
The 23-year-old shot stopper was at fault for two of the Cherries' goals as Posh twice threw away a two-goal lead.
Ferguson told BBC Radio Cambridgeshire: "I wasn't pleased about that, obviously it was a minority, because I thought the fans and atmosphere were brilliant.
"But when they start booing one of my own players, I'm not having that."
Lewis flapped at a corner to allow Danny Ings to grab Bournemouth's opener and then cost his side two points late on by letting Adam Smith's shot squirm through his body.
"I was a little bit disappointed with some of the fans getting on his back," Ferguson added.
"I don't see how that values anyone, it's not as if he deliberately made the mistakes.
"I think he's had a very good season, he's made a couple of mistakes, we just gave to get on with it.
"He's got a lot of belief, he's a top goalkeeper and if you look at the list of scouts that were here on Friday most were probably watching Joe.
"He's a big enough lad, he's got the right temperament, I'm sure he'll be fine."
Posh are now six points adrift of the League One automatic promotion places.
