Yeah pretty much. He was almost exclusively sharing the pitch with both Enzo and Caicedo so he always had Caicedo's legs next to him and Enzo's passing to defer to, so was never asked to be expansive with his passing nor was he ever asked to cover large spaces. His job was essentially to keep it simple, recycle possession and support Caicedo cover off the ball. The clip you posted more or less shows the Santos we saw at Chelsea. I do think he has more to his game though, and his role, when he played, was quite restricted. Hopefully Carrick can bring that out of him more.
I don't think he works well as your sole DM, I think ideally you'd have another, more energetic and quick defensively minded player next to him. Thankfully for us, we had Caicedo who is also a good passer, as well as an elite DM so they complimented and covered for each other really well.
