Not Necessarily. Mikel would be behind De Rossi as the DM of the XI but could still also play next to him which will allow him a bit more freedom and a bit more responsibility offensively like he does for Nigeria. I'd be looking to move Essien before moving Mikel. Mikel, Lampard, De Rossi, Ramires and Van Ginkel (assuming Romeu goes out on loan) is a very solid selection pool. Also allows us to play 4-3-3 quite easily, especially if you conside Oscar and KdB can also potentially play there. Our team is already a million times better depth wise.
