Neil Lennon has urged Celtic's players to prove him wrong after telling the club's board which of them he wants out this summer.
Caretaker manager Lennon confirmed on Monday he had already handed major shareholder Dermot Desmond and chief executive Peter Lawwell the names of those he believes should be sold at the end of the season.
"Ultimately, we have to qualify for the Champions League," said Lennon, who questioned whether his under-fire squad has what it takes to hold on to second place in the SPL.
"I did come out and say what I felt on Saturday; now I want them to prove me wrong. They're playing for their futures here."
He added: "Do they want to stay at this club? Well, they've got six games to prove it."
If the former Parkhead captain's behaviour during Saturday's shock Active Nation Scottish Cup semi-final defeat is anything to go by, Landry NGuemo, Marc-Antoine Fortune and Georgios Samaras may well feature on his blacklist.
NGuemo was hauled of before half-time at Hampden, while Lennon singled out forwards Fortune and Samaras for criticism in what was a scathing post-match press conference.
Whether that trio enjoy a stay of execution in Tuesday night's Clydesdale Bank Premier League game against Motherwell remains to be seen.
Lennon hopes "pride" will be the minimum his players show on Tuesday night.
"We're probably stripped down to the bare bones in terms of that," he said.
"It's a powerful thing though, professional pride, pride in yourself as a man and pride in your performance."
