Blackpool face the toughest task away at Premier League champions Manchester United, Birmingham are at Tottenham, Wigan travel to Stoke while the winner of the huge Wolves v Blackburn fixture will guarantee survival.
"To win the first cup final in the 94th minute, it gives you a real feeling of victory and of joy," Martinez told BBC Radio 5 live.
"It will be a phenomenal achievement to be successful in this campaign because in my eyes it has been one of the hardest seasons we have had in the Premier League."
Wolves boss Mick McCarthy
insists that he is relishing the tension as his side head into the final day with their destiny still in their own hands.
"Am I enjoying it? I am enjoying it all," he said. "What is the alternative - to go and play golf?
"It is an absolutely fabulous job despite all the pressures and attention I get. I don't want to do anything else - I love it."
McCarthy believes that fellow relegation candidates Birmingham may not be tougher opponents than a mid-table side with far less at stake.
"It probably helps that it makes them as nervous as we will be," he added.
"I am never quite sure whether it is a good thing or a bad thing when you go into a game against a team that is relaxed and nothing to lose.
"Does it take the edge off their performance or does it give them an ability to relax with a bit of gay abandon?"
McLeish will not contemplate relegation
Birmingham manager Alex McLeish
is refusing to be distracted ahead of facing Tottenham by speculation linking him with the vacant hot seat at West Ham.
"It's hypothetical stuff. I'm not going to get involved in ifs and buts [about my future]," said the Scot, who guided his team to Carling Cup glory earlier this season.
"But I do know [Sunday's game] is probably the biggest of my career. It is certainly the biggest of my managerial career - so bring it on.
"I believe we will stay up. We have to try and play to the strengths the players possess. We know opening up against a Spurs team could be deadly.
"We've got our own strategy and we have to try and be good on the day to get a positive result at White Hart Lane."
“I'd give my Carling Cup winner's medal back to stay in the league”
Birmingham's Craig Gardner
If Birmingham do end up going down, it would be a sad end to a season which had looked to be a success story after they beat Arsenal to win the Carling Cup in February, a result which means they will play in next season's Europa League.
"The Carling Cup win was fantastic and it's something we will never forget," said
Birmingham's Craig Gardner
, a lifelong Blues fan.
"To lift a trophy for the fans and the club after so long was fantastic.
"But this game is our career, it's bigger than the cup final and we need to go out there and give it every single ounce for this club.
"On a personal level this has been my first full season at Premier League level and it's been a great season for me. But I'd give up every single goal now just to stay in the league.
"In fact, I'd give my winner's medal back to stay in the league."
Blackburn manager Steve Kean
said his team were in confident mood ahead of their trip to Wolves after picking up five points from their last three games.
Goal difference is vital - Kean
Kean said: "Wolves have been quite animated - it's 'Beat Blackburn Weekend', it's 'Survival Sunday' down there - but we want to view it as 'Success Sunday' because we are in good form.
"It's not a case of us fearing going to Wolves, we are going into the game really looking forward to it and to have a really good ding-dong.
"We have been positive against Manchester City, Manchester United and West Ham and we are not going to sit back and play into their hands, and let them batter us with balls into the box."
