The teams played out a goalless stalemate in the Champions League on Wednesday and Mourinho says the onus will now be firmly on Rafa Benitez's side in their Premier League clash.

"In the Champions League we started the game with the same number of points (three) and we had the same objective ... to go into the next round," Mourinho told Chelsea's website on Friday.

"So it was not a bad result for us and it was not a bad result for them.

"In the Premiership the points difference is a minimum eight points (if Liverpool win their two games in hand). So I think a draw for them on Sunday is a very bad result."

Runaway Premier League leaders Chelsea, who have a six-point lead over second-placed Charlton Athletic, have held the upper hand in recent matches against Liverpool.

Mourinho, however, said the Merseysiders deserved a lot of credit for the way they had defended in the last three games against his team.

"In (the previous) six matches Liverpool have only beaten us once and we know in which circumstances they beat us," said Mourinho in a barbed reference to their controversial Champions League semifinal winner at Anfield last season.

"But at the same time we know also that in the last three games we couldn't score (against them) and we couldn't score because they defended really well.

"We have to give credit to a team that defended well and defended with a lot of aggression."

Mourinho said he would have a fully-fit squad to choose from on Sunday and hinted that Spain left back Asier del Horno could return after injury.

"Del Horno played 45 minutes in the reserves on Wednesday and had no reaction," he said.
