Some clubs see the competition as a hindrance, but Cudicini thinks a long cup run can aid the team's title hopes.
"Most of the time, when you have a nice run in the cup, it helps the team to keep concentration in the league as well. I think the two things run parallel," the 38-year-old said.
"In the cup you have a chance to make a few changes and all the players who have come in this season have been ready. Hopefully it will be the same this Sunday."
