"In sport you have to accept you are going to get criticism," he said in response to suggestions that fans are against the continued selection of Walters after just one league goal in open play in nearly 12 months.
"If Jon is not scoring goals then he will get criticism, but he's tough enough and he understands the game. I think the majority of supporters love Jon, but there will always be that group who know better."
Walters, Michael Kightly and Matthew Etherington appear to be battling it out for the two wide places. Whoever plays, Walters says the players know they have to get forward more.
"We can do better going forward and we are working on that," he said.
Walters has netted once in the league this season, but added judging him on goals alone was a little unfair.
