Russell Slade has warned his Cardiff City squad that they are playing for their futures at the club.
The manager off-loaded a clutch of players in the January transfer window and made it clear that there could be further departures in the summer.
Cardiff have 10 Championship games remaining, beginning with Saturday's trip to promotion-chasing Brentford.
"They are well aware these 10 games are important for a lot of reasons," Slade said.
"They understand there is a little bit of restructuring. They saw the restructuring go on in January.
"They knew that next opportunity will be the summer and it's important they work hard if they want to be a part of that process going forward. And I am sure they do."
Cardiff are again set to be without injured goalkeeper David Marshall for the trip to London.
The captain missed last Saturday's 2-1 home defeat to Charlton and is a "major doubt" for the Brentford encounter, but Slade said Marshall should be fit for Scotland's internationals with Northern Ireland and Gibraltar later this month.
Slade also said striker Joe Mason was close to a return to action after a hamstring problem, while Anthony Pilkington and Kagisho Dikgacoi were making progress with their injuries.
After Brentford, Cardiff face another top six side when Bournemouth come to the Welsh capital next Tuesday.
"I am really looking forward to these two games. I am hoping it shows us that we have made some progress and we are moving forward," Slade added.
