Graffiti reading 'Munich 58' was covered up outside Goodison Park ahead of Manchester United's trip to Everton .
The red graffiti references the Munich Air Disaster which claimed the lives of eight Manchester United players and three members of club staff.
More graffiti was also found close by, simply reading 'LFC'.
United can close within a point of fourth-placed Chelsea with victory at Goodison, and boss Ole Gunnar Solskjaer is striving for his side to show the consistency required to secure a Champions League spot.
"We've had a few disappointing games, definitely," Solskjaer told Sky Sports.
"We've had inconsistent periods, we've had some great highs, great games... loads of games we've played really exciting football. And then we've let ourselves down in games we've dominated."
Solskjaer hailed January arrivals Bruno Fernandes and Odion Ighalo with both players in the squad at Goodison.
"That little spark he's given us, he's come in and the feeling around the place is better," Solskjaer said about the Portugal international.
"He plays forward passes, he takes chances. He loses the ball a few times but he's one of the players who looks good when he loses the ball because it's a good attempt, and he wins the ball back. Delighted with him.
"Odion as well, he's given us something extra. We've missed that type of striker who has been in and around the box and having some tap ins.
"We've had to score more or less perfect goals to score. We don't need that now.
"We've got players who can strike the ball from outside, we've got a striker in the box so I feel we're getting closer and closer to that consistency."
