Better buy Idrissa Gana from Everton. Gana is more consistent.
If not Gana. Declan Rice is a better option than Lemina.
Declan Rice has a dominate presence, has the mentality and i think Rice can handle the pressure to deliver high level every week.
For the dcm role. I only see Gana and Rice will do a consistent job in the future.
Outside the continent is Barella.
And Fabian Ruiz. If Ruiz sit more deeper, as a deep dcm playmaking role. With his guts and energy. Those are 4 options im consider for the dcm role.
Gana from Everton - He has definitive the running legs
Declan Rice from West Ham
Fabian Ruiz from Napoli
Barella from Cagliari
High guts, energy, fighting spirit and working hard. Beside football and ball abilities.
Mental aspect abilities + physical abilities + football vision and ball abilities. Im satisfy with those abilities to those 4 players. Some score higher than others in some area. But overall, as a fullpacket as a football player. I would like to have all of those 4 in the squad. Definitely good enough for United squad and will strength the midfield and squad.
Edit:
I will take off Fabian Ruiz from new dcm options. He way too offensive and attacking minded. A more nr.8 than a nr.6.
Then is down to the others 3
+ I.Gana has running legs, good acceleration and really good to break up opponent attack.
+ Barella a allround and complete cm player. Good to tackle, creative and good in the build up.
+ Rice is a dominate player. A central midfield leader pontential, is discipline to sit back. Good air ability in the attack.
Its hard and difficult to choose one of those. United might need for two a but more defensive cm. Herrera and Matic soon. So it would might go for either Gana/Rice + Barella.
Barella is a more of Herrera type of player. Gana is a more Kante type of player. And Rice is a bit more Keane type of player. All of Rice, Barella and Gana are on high international level. And all of them. Barella and Rice will be regular nation cm player in the future. Best in their countries, in their positions. And i think definitive good enough for United too, in the future. Cost more, but lesser risk buy. Future regular and current nation player.
