Bolton goalkeeper Jussi Jaaskelainen is looking to put one over former boss Sam Allardyce on Sunday.
Allardyce will take his present team - Blackburn Rovers - to the Reebok Stadium, the scene of some of his greatest achievements in the football.
The former Trotters manager's eight-year tenure at the club coincided with him leading them into Europe and to the League Cup final.
This Lancashire derby also has the added spice of the fact that Bolton have not beaten their local neighbours at home since 1998.
And, after their 1-0 defeat to Manchester City, Jaaskelainen and his team-mates are desperate to get back to winning ways quickly.
"It's a massive game for us on Sunday," he said.
"When you lose a match it is all about how you respond in the next one. I don't think we have beaten Sam since he left the club.
"Hopefully it will be that time this weekend."
