Will Mateus Fernandes work well with Kobbie?

I have not seen enough of him. I only saw him play when we played West ham. Seems like an 8, which is the position of Kobbie. Now that we are seriously considering him, will he work with Mainoo.

I reckon Tchouameni will work better with Mainoo as he is a natural 6. Don't we need a dm more atm anyways??
