Going all continental, yeah i guess so in a 4231 formation, with the double pivot you have the DM and the grafter (box to box) type, they never stand out but the keep it simple, tend to be the more energetic, up and down the pitch and simple passes.
Gueye at PSG does the same job and Herrera, all that easy on the eye talent around them, they will hardly be noticed, but they'll be a important cog in the team., work hard and get the ball and give it simple.
Like i said all the top teams have that type of player, Fernandinho at City for years and now they have Rodri doing that role, Kovacic at Chelsea, United play a double pivot 4231 Mctominay and Fred combine that role at United, Carrick did the job in that great 00's United side, nothing eye catching but did the simple things which gave the likes of Scholes to do his thing.
