Last week’s loss at QPR allowed Newcastle to leapfrog us into fourth, with Chelsea a point behind in sixth.
Meanwhile, Blackburn are fighting for survival and are second-from-bottom, three points adrift of the safety line going into the weekend’s fixtures.
“The lads were down after QPR, but you have to go back to basics, get motivated and believe you can do the job,” said Ryan.
“You have to take care of your own back yard and that starts against Blackburn. We have to win that game and it’s probably a must-win game for Blackburn as well.
“Blackburn will be really up for it in the position they are in as well. It will be difficult game, we have to be completed ready for it and up for it, and I know we will be.”
Ryan spent seven years at Ewood Park before joining us at the end of the winter transfer window.
“There are some really good players there,” added the New Zealand skipper.
“Junior Hoilett is a fantastic prospect and we all know about Yakubu, he scores goals wherever he goes.
“They have some dangerous players, certainly, but so have we and we have have to look at this game as a potential three points for us.
“It’s a huge game for both teams, a must-win.”
We’re looking to get back to winning ways as we compete with Arsenal, Newcastle and Chelsea for a place in the Premier League’s top four.
