Harry Redknapp knows he is taking his team to face a Blackburn side starting to find some form under new manager Steve Kean.
The Scotsman took over from Sam Allardyce at Ewood Park in December, and Rovers have won three of their last five league games.
Harry is predicting future success for the former Fulham and Coventry assistant manager, and said of tonight’s fixture: “It’s a tough game.
“They’re in good form. Steve Kean has done a good job there and he’s got them playing well.
“It was difficult when he took over from Sam, who’s not an easy act to follow, but he’s done great and they’re playing well. It will be a difficult game for sure.
“The owners brought him in and obviously believed in him to give him the job and I’m sure he’ll do a great job there.”
We will be hoping to repeat our 2-0 success at Ewood Park last season, although Blackburn’s home form in the league this season is bettered only by ourselves and leaders Manchester United going into tonight’s clash.
And Harry is aware that Blackburn’s threat lies in the ability of their players as well as their renowned physical strength.
The manager added: “They’re dangerous opposition and they’re playing some good stuff. You never get an easy game at Blackburn. It’s always a tough place to go.
“The big centre-half, Christopher Samba, is a handful when he comes up for set-plays and when Ryan Nelsen plays they’re a strong, powerful team.
“And they play a bit as well. In midfield they’re playing with a diamond, they’re looking to move the ball around and they’re playing well.”
The encounter is our first since the closure of the latest transfer window on Monday night.
Reflecting on the window, Harry added: "The chairman has always said he would spend the money if we found the right person, there is no doubt about that, but clubs wouldn't sell the players that we tried for in the middle of the season.
“We have a good group of players here already and need to keep pushing on."
