Quite obvious? Mourinho already said Cuadrado's transfer was a result of Schurrle's departure. How obvious more do you want?! Also, you do remember that we only confirmed the Cuadrado signing after we successfully sold Schurrle to Wolfsburg, no? Regarding Salah, he cleary wasn't impressing Mourinho and was never going to get consistent game time (the main reason why Schurrle left in the first place). Hence, he was used as a bargaining tool to get a cheaper price.
