Chelsea have three wins from their last 10 matches and are without a victory in four ahead of the Premier League clash with Wigan, with their latest slip coming in a 3-2 defeat against Newcastle last weekend.
It is hard to tell whether owner Roman Abramovich is losing patience with Benitez, who replaced Roberto Di Matteo in November, but never in his 10-year tenure has the Russian had three managers in the same campaign.
The Blues would slip to fourth ahead of kick-off against Wigan if Tottenham beat Newcastle in tomorrow's lunchtime match.
"We know the problems and we are working on the solutions," said Benitez, when asked if he expected to see out his short-term deal until the end of the season.
"The main thing is that you can score two goals, and then you are 2-0 up at half-time, then you have to finish the games.
"Against Newcastle we scored two goals, you cannot make these mistakes (to concede three). You have to make sure we control the game.
"We could have won all the games we didn't win. It's a question of sometimes doing the right things at the right moment, having a little bit of luck, being more clinical, not making mistakes in defence.
"The team is doing well in terms of the performance and we have to improve the results, especially the games we were winning."
