Considering team management strategies

I'm suggesting minutes management and rotation for Copa and Liga, and promoting youth players like Marvel and Carrillo. For center-backs, I have Marvel, Alvaro Carrillo, and Vinicius Tobias as right-back. I’ll focus on formations like 4-4-2 or 4-2-3-1 out of possession, transitioning to a 3-2-5 shape in possession with inverted full-backs. It's also crucial to emphasize counter-pressing and foul management during transitions. Plus, we need to manage set pieces effectively, positioning players like Rudiger for aerial threats. I'm reminding myself to keep injury updates in mind while avoiding outdated specifics given the information cutoff in October 2024.Structuring team strategy advice

So, after Nacho's departure to Al-Qadsiah in summer 2024, Real Madrid signed Leny Yoro as a center-back but there were rumors about Alphonso Davies that didn’t finalize before the cutoff. My advice needs to be structured and clear. Here’s what I want to propose:

• First, diagnose the current situation: we're dealing with a high line and aggressive rest defense that's being undermined by injuries, along with a thin rotation, especially if Arnold is out.

• For the immediate plan over the next 4-6 weeks:

  • Lower the block for tough away games, and use a mid-block at home.
  • Implement Mendy as a stay-home left-back, and consider using Valverde as an auxiliary right-back to support Mbappe's side. We should protect Mbappe with Mendy behind him.Organizing defensive strategies

I think Mendy is solid at left-back, and we can rotate Camavinga between left-back and defensive mid. In possession, I want to propose a back three with Lucas Vazquez as right-back if Arnold is out. Valverde can cover the right channel as RCM, while Tchouameni might shift to right center-back. If Carvajal is fit, we could alternate him with Vazquez.

For defense, we should use a 3-2 shape with Tchouameni and Valverde as the pivots. I also want to set pressing triggers wide to force the play outside and protect the center.

For personnel, if we’re thin at center-back, I could drop Tchouameni and call up Marvel or Carrillo while capping Rüdiger's minutes. I see Mbappe as an outlet but want to reduce his depth tracking, assigning Valverde to cover his zone and adjusting the shape to a 3-2-4-1. We might also consider a 4-4-2 diamond for certain matches.Developing tactical and transfer strategies

First, we should avoid using the diamond formation until our right-back is healthy, as it exposes the flanks.

For set pieces, we can implement mixed zonal-man marking with specific first contact assignments, focusing on blocking opponents and ensuring a near-post runner.

In training, I suggest incorporating microcycles with small-sided transition games twice a week to improve defensive line cohesion and synchronize the offside trap.

Regarding transfers, we might explore short-term free agents or possible loans for a right-back like Iván Fresneda, and consider Castilla promotions instead of speculating on free agents.

I need to establish key performance indicators such as PPDA, expected goals against (xGA), shots conceded within the box, and set-piece xG conceded.

Lastly, I want to clarify if the user is looking for a tactical plan or transfer suggestions, so I’ll ask for confirmation on names and timeframe at the end. I’ll keep the analysis concise and formatted for clarity.
