But the 29-year-old Frenchman, who has just been voted Blues' player of the year by his team-mates, is confident Carlo Ancelotti's side will not slip up at home to Wigan tomorrow.
"Nobody here even thinks about anything other than a victory. To fail would be a disaster," he said in the Daily Mirror.
"For me, it would be the worst blow in my career, but with our fans at Stamford Bridge behind us we believe that's impossible.
"If you analyse the numbers and statistics in our season, then Chelsea deserve to be champions and yet we know we must still win on Sunday to confirm our achievement.
"We will forget the nerves and we know we will have to play with our heads and be patient. I am totally convinced we will be champions."
If Chelsea do lose at Stamford Bridge, Manchester United could get their hands on a fourth successive league title by beating Stoke at Old Trafford.
Malouda added: "We know Wigan will not give up against us, but our chance of winning the title should be big enough to overcome any obstacle placed in front of us.
"The key to beating Wigan will be to score the first goal. We must not think about Manchester United and for Chelsea the only interest is our match."
