Eintracht Frankfurt manager Michael Skibbe has warned his players to step up their efforts in pre-season or face the prospect of being shipped out.
Frankfurt finished just three points off the drop zone last term and it seems they have taken their dismal end of season form into pre-season.
A number of poor performances in pre-season games in recent weeks seems to have tested Skibbe's patience and he is set to wield the axe.
The Frankfurt chief has been told he must lower the wage bill this season and he looks certain to get rid of some of his squad before the Bundesliga campaign begins.
"It's not that I wouldn't be willing to see players committing errors, but this patience is nearly up," he told Frankfurter Allgemeine Zeitung.
"If there is one (player) that does still not know how to do it, then he is not part of my team any longer.
"If there is someone thinking he can do what he wants to, if there is one that is not keeping an eye on my slogans, then he is the one that has to leave.
"I am considering singling out four of five players that are well down my pecking order.
"And that could happen before the start of the season. These players are then able to consider if a transfer to another club would not be a better option for their future careers."
Meanwhile new Frankfurt goalkeeper Ralf Fahrmann has been ruled out for at least six weeks after breaking his hand in training.
The shot-stopper was highly rated at former club Schalke but could not shift number one choice Manuel Neuer and joined Frankfurt on a Bosman in order to play first-team football.
"This is a blow, for the club as much as for me personally," Fahrmann told Frankfurter Rundschau.
"But I am confident it will not be more than a stepping stone in the long-run."
