Portsmouth boss Harry Redknapp has warned his squad they cannot allow themselves to think things will get easier after a tough opening to the season.
"It's another easy one for us, isn't it? I don't think so. Mark has done a good job at Blackburn and it is one of the last places you want to go. There are no easy matches at this level and this one certainly isn't.
"Blackburn have terrific players and a way of playing that is very difficult to combat.
"They have people with a lot of physical presence but also a lot of skill. Their record speaks for itself."
