Blackburn came away with draws in both those games as part of a five-game unbeaten run which has seen them pushing for a top-10 finish as the season draws to a close. Everton have enjoyed a considerable upturn in form themselves though, fighting back from an injury-hampered start to the campaign to mount a challenge for a place in Europe. David Moyes' side have drawn their last three games - against Wolves, West Ham and Aston Villa - where they might have won, but they are undefeated in seven and have beaten both Chelsea and United since Christmas. "While Everton are not in the top four, they are the in-form team in the Premier League at the moment," Allardyce said. "I think David has lost only two in 19 Premier League games. I watched them at Wolves away and they should have won that game comfortably, missing chances on the day, and I watched them at Villa on Wednesday night. "I'm thinking this game is going to be as tough as the Manchester United and Chelsea ones." Allardyce has earmarked Tim Cahill - who scored two trademark headers in the 2-2 draw at Villa - as a player his team will have to give some "careful attention" at Ewood Park. "He is exceptionally good, particularly in the air as we saw," Allardyce said. "He is a very determined player who is very brave. I think that, coupled with his ability, makes him a real threat in the goal area and he can jump higher than anyone else - that is what makes him so dangerous. "He will need some careful attention, in the box particularly." Cahill will be looking to find a way past Rovers goalkeeper Paul Robinson, who has kept two of the team's three consecutive clean sheets and is determined to help them maintain the momentum in their bid to seal a top-half finish. "We were safe 10 games ago, but we seem to keep churning out the results," Robinson said. "We are enjoying playing our football and we are enjoying getting those results. We want to win that middle-of-the-table league. "There is Fulham around us, Sunderland, Stoke - we want to get into the top half of the table and really push on."
