It has been reported that Capello, whose team had a disappointing World Cup campaign in Brazil over the summer, is owed outstanding wages by the Russian Football Union stretching back over the last three months.
But, asked about that at his press conference to preview Monday's home game, Capello - quoted by sport-express.ru - said: "In the case of all rumours about my contract and about money, I am not thinking about it because the financial issue is what I care about the least.
"All my thoughts are about football, about the upcoming match with Liechtenstein."
Liechtenstein have finished bottom of every European Championship qualifying group they have taken part in, but Capello is adamant Russia will not be getting an easy ride on Monday.
The Italian said: "Liechtenstein are a pretty aggressive team.
"They play with great dedication. These opponents are difficult, and it will not be easy for us.
"Probably in our line-up there will be some changes, but I will not say what."
Russia skipper Vasili Berezutski also feels it would be wrong to assume that the contest will be a guaranteed home win.
The 32-year-old defender, who was part of the team held to a 1-1 draw by Azerbaijan last year in a World Cup qualifier, said: "Liechtenstein and Azerbaijan are on about the same level.
"Perhaps 10 or 12 years ago, you knew exactly what to expect and that you were going to win in some games.
"But now you can have no such certainty. Weak teams no longer exist."
Russia are the only side in Group G that made the World Cup finals, but Sweden came close, missing out after being beaten in the play-offs by Portugal.
The Swedes make their return to competitive action on Monday - a few days on from striker Zlatan Ibrahimovic becoming their all-time top-scorer by netting a brace against Estonia - with a clash against Austria in Vienna.
Marcel Koller's men came third behind second-placed Sweden in their World Cup qualifying group and Austria defender Sebastian Prodl is keen for the team to make a big impression against their opponents on Monday.
"We must show that we are their equals," Prodl said, quoted on www.oefb.at.
"We want to set the tone in our own stadium, in front of a sell-out crowd."
Monday's other Group G match sees two other nations that were in the same World Cup qualifying pool go head to head again as Montenegro host Moldova.
