The Rovers boss was disappointed with his side's poor display at the Hawthorns, but is hoping for a turnaround against Kenny Dalglish's team, who may have their eyes on the FA CupBlackburn manager Steve Kean is hoping that Liverpool will be distracted by their FA Cup semi-final clash with Everton when they travel to Ewood Park on Tuesday evening.
Rovers have been sucked back into the bottom three following a run of three successive league defeats, but the Scot is wishing that an out-of-form Liverpool, with just one win in their last nine games, are already turning their attention to Wembley on Saturday.
"There is no reason why we can't go out and beat Liverpool," Kean told reporters.
"Liverpool will have an eye on the FA Cup so us playing them now is a good time.
"If we can put the first 80 minutes against Man United and the first 20 against West Brom together, we can certainly get a result"
"But they have got a very good squad, I have seen them live a number of times this season and they normally start the games very well and have had spells where they just haven't scored.
"Then their opponents have managed to get themselves in front and it has been difficult for them. But it hasn't been the case where they have played poorly."
Kean remains optimistic regarding his players' ability to beat the drop this season, but is demanding a vastly improved performance than that which was given in the 3-0 defeat against West Brom on Saturday.
"We might have got away with having a bad result from this round of games because we've not lost any ground," he continued.
"We have got a very good dressing room with characters in it that want to win and stand up for each other and themselves.
"But we know we can play better than in the first half at West Brom. We need to make sure we analyse the reasons for that poor display and get back on song against Liverpool.

"We have to bring that to the players' attention and try and spark ourselves into life a lot quicker.
"If we can put the first 80 minutes against Manchester United and the first 20 minutes of the second half against West Brom together, and have an overall performance, we can certainly get a result.
"But there are going to be a lot of twists and turns in this relegation battle before anything is sorted."
