Guardiola pretends hed rather play man united with rashford
I think you may be mistaken! Pep Guardiola is the manager of Manchester City, not Manchester United, and he has consistently shown his admiration for his own team and players.
While Marcus Rashford is a talented player, it's unlikely that Guardiola would pretend to want to play with him for Manchester United instead of his own team. Guardiola has built a strong squad at Manchester City and has a deep understanding of his players' strengths and weaknesses.
It's possible that you may be thinking of a different manager or scenario. If you could provide more context or clarify what you mean, I'd be happy to help!
