The Torquay United manager said his side were well off the pace in Somerset after their good recent winning run came to an end.
Johnson lavished his team with praise after they strolled to a 3-0 win at Wealdstone on Saturday.
But against the National League South’s bottom side it was a totally different story as they escaped the Woodspring Stadium with a point.
“You don’t want my thoughts on that performance!” he told the club’s media team when asked to reflect on a challenging night.

“Weston had too much of the ball in the first half but we got ourselves back in the game without playing well.
“It was scrappy and hard to watch at times, we really didn’t play well, which a surprise as we have been lately.
“But there is one positive for me and that is that we saw how big this club could be if we get a team out on the pitch,” he told the club’s website.
“The support away from home on a Tuesday night was incredible and it shows how good things could be if we do get it right.”
