Wigan's Melchiot convinced they can do Chelsea favour
"We need the points ourselves and may have to win to stay up. We want to get our future secured by then but it might all come down to the last game.
"Part of me is sad I may have cost my old club in the title race. I always get a lot of love and respect from the fans at Chelsea and I want nothing more than for them to win the title, but I had to do my job for Wigan first."
But while Chelsea may have lost vital ground in the title race, Melchiot believes they can reach the Champions League final.
"The first leg will be difficult - Chelsea have struggled for years at Anfield - but they can finish them off in the second leg," he said.
"I think they can go all the way. They have better individual players in the team now and it is time they got to the final."
