Hamworth has always thought City would go up with Wigan. He's looking at play off success for Tranmere.
"I still hope Tranmere can go up via the play-offs, while I think Cardiff will take one of the two promotion spots. It was always going to be Wigan and Cardiff before the season started and I see no reason to change now.
"Wigan are just about up and Cardiff will join them. We played Crewe recently and Cardiff are the better side. If they want it badly enough, and I'm sure they do, they will finish in the top two."
Haworth scored his 18th goal of the season against City but the hero of the night was Robert Earnshaw witha hat trick to take his tally to 32 goals.
"Earnie was always the threat for Cardiff," said Haworth. He plays off the back of defenders, he's quick and puts his chances away.
