Sam Allardyce has called on Everton fans to get behind him after their win over Newcastle.
"You get that bit of controversy and I think as a manager you just deal with it and move on. I don't dwell on it. We've moved on, I've got no gripes against who did it, it's gone, let's not let it happen again, let's move forward.
"But the players did all the talking, I'm glad to say, by winning the game again at home and putting us up to eighth place and hopefully (we will) finish this season as strong as we possibly can."
The hosts' only shot on target proved to be the winner as Walcott engineered some space following Yannick Bolasie's deep cross and rifled into the roof of the net.
Newcastle, who had won four games in a row, almost conjured up a last-gasp equaliser but Jacob Murphy's cross was brilliantly headed away by Seamus Coleman.
Asked for his assessment of the performance, Allardyce added: "I think up to 75 minutes, excellent. And then we had to do a little bit of desperate defending to secure the victory that we deserved.
"Breaking down a very stubborn Newcastle defensive unit, with all players in their own half trying to suck you in and hit you on the break, was difficult. Finally we did it.
"Theo's come up with his third goal since he arrived and it was the winner. I'm pleased for him and pleased for the team."
Newcastle's recent good run has lifted them well clear of relegation trouble and their safety is virtually assured already, even if the point they need to guarantee it eluded them on Merseyside.
