Ian Holloway has hit out at QPR fans for jeering Ben Gladwin and urged them not to do the same to Conor Washington.
Striker Washington has endured a difficult first year at Rangers following his move from Peterborough.
He has returned to training following an injury and Holloway believes Washington can make an impact at Loftus Road.
But the Rangers boss is concerned that Washington could suffer the same fate as Gladwin, who has been unable to win over Rangers fans.
Holloway recently decided to loan Gladwin back to his former club Swindon, where he has made an immediate impact, scoring in a 2-1 win at Bolton.
“He (Washington) is a huge part of my plans – I just want people to be patient,” Holloway told West London Sport.
“Gladwin’s gone back to Swindon and scored a goal because the Swindon crowd like him.
“I don’t feel he (Gladwin) can ever score for us when they keep on chanting at him like they did when I gave him a chance.
“Is it rocket science? Are Bolton that far away from us? How can he play for Swindon and score a goal? Work it out yourselves.
“If you had a teacher who screamed at you ‘you’re crap, you’re rubbish, you’re crap, you’re rubbish’ could you actually achieve anything? I don’t think so.
“That’s all I heard and I thought it was unfair and I’ve got to loan him back.
“I was getting pelters. It’s really annoying. I don’t mind that you pay your money and you like certain people and don’t like certain people, but just shout to the ones you do like.
“That wouldn’t half make my job easier instead of picking him up from the floor. I had to pick him up by his braces a couple of times.
“Is he that bad? I don’t think so. Has he got a chance here? I don’t know if people are taking to him like that.”
