Fernandinho!
Has to be, imo.
Others have had good games, good periods but Dinho has been consistently good all season. Only a handful of dodgy games.
How many games has he been MOTM in? Loads. Big games too. And even in some of the games other players, like KDB, have won it, Dinho has been a close 2nd or 3rd.
He's also worked his bollocks off more than anyone in the squad (probably since he's been here)
