The Mannings Ground club have blasted 15 straight wins since their season-opening 26-12 Gloucester Premier defeat at Whitehall.
McArdell’s men have racked up 137 points in their last three encounters, including their 47-13 Senior Vase victory at Devon side Teignmouth.
But despite that stellar form, Hartpury College further education sport lecturer McArdell thinks it will have no bearing on tomorrow’s clash at Marlborough (kick-off 2pm).
Not even consecutive 45-0 victories over Painswick and Gordon League leave McArdell expecting anything other than an intense battle against the Wiltshire men.
McArdell said: “It’s been a long time since we’ve lost now, and we’ve got a good run going.
“We’ve got a good team out tomorrow and hopefully we’ll be in good shape.
“Obviously that gives us confidence, but they are having a good season as well and they will be extremely up for this game as well.
“We can’t take too much notice of what they’re doing, they’ve been winning well too, but it’s always hard to compare leagues.
