Campbell featured in the reserves clash with Liverpool.
Beardsley told the Evening Chronicle: "For people like Matthew Grieve to play alongside a former England player is great.
"For Jeff Henderson to come on and replace a player like Sol Campbell may only seem a little thing, but for the young players they are massive. When people saw him jogging off the other night he then made a point of going to see Jeff before he came on.
"When you're a young player and somebody of Sol's stature does that it means a lot."
