Patrick Roberts could understand why the Celtic fans reacted angrily following their goalless draw with Dundee - because he has done the same himself.
The on-loan Manchester City winger's first start ended in a crescendo of jeers at Celtic Park on Wednesday after the home side saw their lead over Aberdeen at the top of the Ladbrokes Premiership cut to four points following a second consecutive draw.
"It's not what you need," Roberts said. "At any club you don't like hearing boos in the stadium. But you can feel their frustration.
"We see it on the pitch ourselves, we are annoyed ourselves. It was a devastating draw so we have to pick ourselves up."
The 19-year-old - a £12million signing by Man City from Fulham last summer - is confident he will rise above the negativity ahead of tomorrow's William Hill Scottish Cup quarter-final clash with Morton at Parkhead.
"Personally it doesn't affect me, I try to stick to my job," he said.
"I get as frustrated as anyone, I'm like a fan on the pitch. I get angry at myself and I get angry when we're not winning. It's just how I am.
"I've been sat in the stands a few times myself watching games and got angry with players on the pitch. So I can sense their frustration."
Roberts insists the players are fully behind under-fire manager Ronny Deila.
"Every player is giving 100 per cent, you can see that in training and they try to bring that to games," he said.
"Maybe it's pressure from Aberdeen behind us, I don't know, but we are not playing to our potential. The title is close but we have confidence in ourselves to get the job done."
Roberts knows a league and cup double is a "must" and he fully appreciates there is no room for error against Morton.
"They beat Hibernian the other day 3-0," he said. "Whoever you are playing against you have to have the same mentality, to go and put them to the sword."
