Why did Alonso, Mascherano and Torres all outgrow Liverpool?

look, Alonso was sold because of Liverpool's financial problems and both Mascherano and Torres wanted to get out of liver pool as soon as possible just to play in a good plan with good teammates with good coaches. and in my opinion since Xabi alonso was sold to real madrid liver pool didn't play well and there was something missing in their plane so what liver pool is in now because they sold Xabi alonso
