Tommy, played by Chris Fountain, has made no secret of his feelings for Tina since arriving on the cobbles earlier this year. However, Matt has also been tipped to start pursuing Tina later in the summer.
Pondering which of the men Tina should be with, Keegan told Soaplife: "Maybe Tommy, because Tina's been in a stable relationship so it's good for her to have some fun and they get on well as mates as well.
"But I don't want Tina to get messed around, which I think Tommy would do and Doctor Matt wouldn't. Then again, that might be too settled for her and maybe she shouldn't be in a relationship like that just yet!"
"She feels there could be something there, but she knows what Tommy's like," Keegan said. "He's a bit of a player, a ladies' man and she doesn't want to get into that again. She doesn't trust guys anyway and she'll find it difficult to trust Tommy if anything more happened."
Of Tina's feelings for Doctor Carter (Oliver Mellor), she continued: "She definitely fancies him. Everyone on the street fancies him - it's hard not to!"
Matt was recently tipped to show a darker side as his storyline with Tina develops.
