27-year-old Cook, who scored twenty-eight goals in forty-five first-team appearances for Rovers last season including bagging a goal during the side's National League Play-Off Final victory over Boreham Wood, will officially join the Saddlers on Sunday, 1st July after turning down a new deal with the Wirral-based side.
Cook, who was speaking via the club's official website - Saddlers.co.uk - said; "I’m a little bit shocked. I’ve only just left and I didn’t think it’d be that quick that I’d go back to play against them. I didn’t actually watch the draw because I was in the gym. I got a text when I came out to say we’d drawn Tranmere – I couldn’t believe it!
"It’ll be nice to go back and see what reaction they give me. I’d like to think I’ll get a good reception after what I did when I was there. I’m just going to treat it as any other game. At the end of the day, I’ll be going as a Walsall player and my ambition is to go and beat them. I can’t wait."
