Smith took the man of the match award for the defeat by Liverpool which was booed by home fans.
"I don't think fans were having a go at players too much, the fans just want to do well so badly.
"We are the ones who can turn it round and can't blame fans too much for being disappointed.
"The fans went there with expectations high looking for a big performance, and it didn't happen. It's not nice because you want your fans behind you, but we must put that right."
