Dorrans indicated he would like to leave Albion this month but has started the last three games and impressed in the 2-2 draw with Aston Villa.
Clarke said: "The reason he wanted to go was that he wasn't playing matches. Now he's playing matches.
"You've seen his performances. He's always 100% committed to the club. I would love him to stay here.
"I hope he's getting enough football to make him reconsider through this transfer window and that he'll stay until the end of the season."
