I think there's a somewhat absurd focus on numbers, number this and number that. When was the last time we had an attacking midfielder supplying goals galore. We didn't need it the last time we dominated the league.
Matic doesn't need someone next to him that closes the distance to the no 10, he doesn't need someone to also provide a goal threat. What you need is movement. Midfielders who can hold on to the ball, pass it into the right path, make themselves available to receive it again. There's too much distance between the players, the passing is too slow and when a player receives the ball there's limited options because the movement is static.
Matic was involved in a situation that is a decent example, he passed the ball up to one of the forward players (don't remember who) who had two defenders on him, he passes the ball into space where he expects Matic to move (and where should move), but Matic expects it to be passed straight to him so a Huddersfield player collects it instead. If there isn't enough player movement, it's bloody easy for the opposition to mark our forwards. You pass it, you move into space to receive it, and if you can't receive it another player should be making himself available at the same time.
We barely have that, at all. If you look at the Benfica match, the Huddersfield match, how often Mkhi runs up and stands next to Lukaku, surrounded by players, waiting for the ball. It's absurd. All it does is make crowded area even more crowded. He has to move further down the pitch, make himself available for the pass, free up space.
We solely depend on individuals. Give the ball to someone and hope they pull off something brilliant.
