Tranmere manager Ronnie Moore admits he has had a 'word in the ear' of some of his players who think they are better than they are.
Rovers were previously leading the standings but have slipped down to third place after back-to-back defeats to Carlisle and Leyton Orient.
Moore feels his players were beginning to overplay and has urged his side to keep things simple ahead of Friday's visit of Shrewsbury.
He told Sky Sports: "Our football has been fantastic this season. But we're overplaying a little bit at times now.
"I think one or two think they're better than they are. We've got one or two Bobby Moores now that we never had at the start of the season.
"People are getting on the ball, trying to dip their shoulder, defenders aren't doing the right things in the right areas. So we've had a little word in their ear."
Despite successive defeats, Tranmere remain just two points off leaders Bournemouth in what is shaping up to be a tight battle for automatic promotion.
Just four points separate the Cherries from seventh-placed Yeovil and Moore added: "One of those teams are going to miss out, we'll just have to make sure it's not us."
