No they wouldn't, including me. Because Herrera is not a DM. There seems to be a seriously poor understanding of what type of player Herrera is. Matic and Herrera are nothing alike, this comparison is just daft.
As I've said before, it's been Herreras position that has been dropped, not the player. As soon as Mourinho decides to play a 3 man midfield or wants a ball winning midfielder he'll be one of the first players on the team sheet because, quite simply, no other player can play that role as well as Ander.
Fans were vocal because he deserved the plaudits and quite rightly received the player of the year award. It seems now the fans who were calling him average and were silenced last season are desperate to try and be proven right.
