The Gers were beaten 2-0 by Motherwell at Hampden last time out, denying them a place in the final of the Scottish League Cup against Old Firm rivals Celtic.
Two second half goals from summer transfer target Louis Moult were enough to end Rangers cup run at the penultimate hurdle.
And understandably, the man in the Ibrox hot-seat is facing tough questions regarding his inability to go on a meaningful and long run of victories.
Caixinha coming under pressure may seem a little harsh given they have only lost two of their last nine games. However, coming up short against Old Firm nemesis Celtic and Motherwell in the cup just won’t do for the Glasgow giants.
Taking on Kilmarnock at home should be an easy enough task, the Ayrshire side are second bottom with just one win all season. Yet that did come last time out when they beat Partick Thistle, just a few miles away in Maryhill.
In Rangers four home games this term, they have won only once, and that was against Dundee. Defeats to Hibernian and Celtic plus a draw to Hearts has put increased pressure on the Portuguese boss.
“I don’t know if I can call upon all 11 players who started on Sunday but if I can they’ll be the 11 who start on Wednesday,” Caixinha told press after the Motherwell defeat.
“People talk about pressure. Pressure is someone who has no money to pay the bills or feed his family and give them education.
“Playing in front of your fans in a semi-final or key fixture needs to be something that creates passion to enjoy it rather than the opposite.”
Fabio Cardoso is a huge doubt after picking up a knock on Sunday. Ross McCrorie is expected to come in to replace the centre-back. But veteran Portuguese defender Bruno Alves will be available, as Rangers are in the process of appealing his two-match ban for an alleged swipe at Motherwell's Louis Moult on Sunday.
