Just two years back Liverpool has the combination of Xabi Alonso and Javier Mascherano at the center of their midfield - arguably one of the best holding and defensive mid-fielders in the world at that time.
In just two years time, it is their departure that is being cited as one of the reasons for Liverpool's downfall, Alonso's more than that of Mascherano.
Lucas has improved by leaps and bounds this season. Meireles, initially bought to play the central mid-fielder role, has excelled in his more advanced role, leaving Gerrard to play at the center of the field.
