Lancel's evil character Frank Foster finally gets his comeuppance tonight (March 5) as he is found dead at Underworld, sparking a murder mystery on the cobbles.
Speaking on Lorraine this morning, Dynevor praised Lancel for his work on Coronation Street over the past year.
The 48-year-old, who plays Frank's jilted lover Sally Webster, commented: "It's been a great storyline. Frank Foster's been such an amazing character. He's been so dark and sinister, and it's been such fun to do."
Supporting Lancel's 'Villain of the Year' nod, she added: "He's got to win that, because he really is such a great villain. I think he'll definitely win that!"
As announced last week, Lancel has made it onto the 'Villain' longlist with 14 other nominees, including co-stars Kate Ford (Tracy Barlow) and Natalie Gumede (Kirsty Soames).
Meanwhile, Dynevor is in the running for this year's 'Best Actress' prize.
Asked what it would mean to win, she replied: "It'd mean a lot, actually. After 26 years, it'd be a wonderful thing to win. I'd be over the moon."
Coronation Street airs Frank's final episodes tonight at 7.30pm and 8.30pm on ITV1.
