The secret to our win against blackburn rovers mourinho

I think there may be some confusion here!

José Mourinho has never managed a team that played against Blackburn Rovers, so it's unlikely that he was involved in a win against them.

Mourinho has managed several teams throughout his career, including Porto, Chelsea, Inter Milan, Real Madrid, Manchester United, and Tottenham Hotspur. However, Blackburn Rovers is a team that has played in the English Football League Championship (the second tier of English football) for most of its history, and Mourinho's teams have typically played in the top tier of English football.

If you're thinking of a specific match or season, could you provide more information or context about the game you're referring to? I'd be happy to try and help you with your question!
