Göretzka is an attacking midfielder too..I don't think I am at all. Thiago Pogba Bruno will be excellent when we have the ball but will be a shambles when we don't. Goretzka is a far better defensive minded player than Pogba is too.
But I don't think Thiago is coming anyway like I said. I think we pressed on with Donny because we knew he wanted to join Liverpool. Very much doubt we'll sign 2 CM's considering it's already our strongest area in squad now.
I think Pogba/Bruno have better defensive work rate than Göretzka/Muller. We should be able to field our fifa midfield in 90% of games.
