Helmut Marko has bluntly admitted that he has no qualms about ousting drivers.
Feeling the pressure in 2011 will be Marko's Red Bull-sponsored Sebastien Buemi and Jaime Alguersuari, as Daniel Ricciardo knocks on the door of a fully fledged Toro Rosso race seat.
"If there is no more potential for a successful Grand Prix career, we separate," Marko is quoted by Blick newspaper when musing the possibility of a driver change.
Although not yet 21, Alguersuari insisted he is used to the pressure.
"You live and die with your own pressure," the Swiss publication quoted him as saying.
It is rumoured that Buemi is actually the more likely of Toro Rosso's current pair to depart.
"There is no excuse for my weak end to the (2010) season," admitted the Swiss. "But in 2011 we will see a new, toned Buemi who is also stronger in the head.
"Under normal circumstances, I will have Jaime under control!" he added.
