I actually think that in his system Maresca likes his midfielders to be the killers. Jackson is the most natural to break lines and get in behind, but often his decision making and subsequent touches are poor. With players like Nkunku getting the ball to feet and dropping off it allows those attacking midfielders to ger beyond and create overloads in an around the box. Tee system, of course, also relies on the non inverting FB to get beyond int he flanks to create width, overloads and therefore act as the one breaking the lines. Gusto shows promise in doing this, but i am not totally sure of Cucurella's consistency in doing this.
Oh, and not wishing to put a downer on last night, but Veiga to me was pretty awful in all that he did , except one decent pass that started the first goal. And the Chilwell experiment flopped totally as we completely dominated the entire game and yet Chilwell came on and was still able to disappear. So that non-inverting FB from the left hand side may still need some work.
The important point though, is that Maresca has all of the pieces here to make this work. Yes a more clinical striker would add so much to our game, but, all being fit, there are still two potent front lines there.
