I am wondering if it could just be as simple as sitting the two CB's deep and our no 6 as a deep lying playmaker just above the cb's. Keep 3 back at all times for a prolonged period of the game, leaving space where our no 6 usually is for the opposition to exploit and play into. Which could bring them out and play into our hands? It's all about setting traps against the weaker teams. We can press and press and press against them but they will always go route one and direct. Maybe instead of gegenpressing, we just press with our attackers, as realistically this is where they'll make their mistakes, as they are poor players in comparison. If we don't win possession back through our attackers we let them come at us in midfield and defense, with both banks structured, deeper than usual and hard to break down. It makes no sense to press a midfield that will 9/10 times be bypassed in my opinion. Counter their strengths and we will easily take advantage of their weakness.
Its a good shout. And also, to be honest it really depends on who you have playing that deepest midfield role or DM as it is sometimes called.
Jordan Henderson is not a natural DM, who knows when to snuff out opposition attacks. He is a converted box-to-box midfielder. You upgrade that position and the effect on the team could be quite dramatic.
You are right as well though, that this new player could sit a little deeper, especially if they also have a good skillset in passing the ball; which may well be essential there.
Outside of this, Klopp's system will work much better with upgrades on both sides at full-back, especially attacking wise. The addition of another quick winger would be a massive help as well. And more essentially a very substantial signing to partner Matip, at left-side centre-back is also essential.
In short: Upgrade the first team. Shift some good players to the bench AND buy one or two youngsters to add to the plan B, C situations.
Done. Go home. Fuck the prom queen.
It might be as simple as buying a specialist for that position and bringing Jordan in as a squad player or box-to-box option as need be.
