Blackburn Rovers boss Steve Kean is targeting two wins from their three remaining games to try to avoid relegation.
Rovers are three points adrift of safety and the Scot's target means the Lancashire club will have to pick up at least three points in one of their away trips to Tottenham and Chelsea. Rovers' run-in also sees them face fellow relegation battlers Wigan Athletic at home.
But despite the difficult fixture list, Kean is adamant his side have the ability to cause an upset at one of the London clubs.
"We need to win two of the three games, so including one of those against Tottenham and Chelsea," he told reporters.
"It's a tough schedule on paper but at this time of the season form goes out of the window. It's just about performing on the day.
"We have gone to Old Trafford, Anfield and Goodison Park and got results this season so we know we can do the same at Tottenham and Chelsea."
Blackburn’s crucial run-in begins at White Hart Lane this Sunday, and the 44-year-old believes he has come up with a plan to add more misery to Tottenham’s poor run of form which has seen them fall out of the Champions League places.
"We have been looking at weaknesses in areas which the players we have available can cause them problems," said Kean.
"We have done our work and have decided how we want to go about the game tactically and a couple of things we can exploit in certain areas of the pitch against Tottenham.
"We know the prize at the end of the season for us is massive. We have to try to keep the spark and enthusiasm we showed against a very good Norwich side last weekend."
The Glaswegian is also pleased with the scheduling of this weekend’s fixture list as Rovers' relegation rivals – Aston Villa, Bolton, QPR and Wigan – will have played before Blackburn’s game against Spurs.
He said: "It's a big weekend, and we will know the outcome of a lot of games before we play.
"Things could be sitting really good for us, it could be much the same or a little bit tougher.
"I will be at Wigan because we have got that game coming up next week and I want to have a look at them."
