Considering squad reinforcement strategies

The user shared a message in Chinese about Chengdu Rongcheng's struggles in the CSL and FA Cup, implying they’re looking for analysis or advice on transferring and strengthening the squad.

I should provide recommendations on squad planning, focusing on positions to reinforce and considering both domestic and foreign players within budget. It's important to suggest tactical fits without getting into specific rumors. I'll mention needed signings like a left-back replacement, a DM/CM to cover Zhou's role, depth at CF/winger, CB, and GK.Clarifying coaching details and tactics

I'm considering the U23 policy in the CSL, along with foreign player quotas and salary cap rules. It’s important to note the tactical notes related to the coaching situation. I seem to have been confused about Chengdu Rongcheng's coach; I initially thought it was Seo Jung-won but confirmed it's Xu Zhengyuan. I should focus on the tactics, possibly a 3-5-2 or 4-2-3-1 setup, and mention that Chengdu often played 4-4-2, utilizing forwards like Felipe Silva and Romulo.Outlining squad actions

I’m thinking through the actions for Chengdu Rongcheng based on their team style, which focuses on being compact with strong transitions. We need decisions on a few key players, like Zhou—should we keep him or replace him? If he leaves, I’ll look for a domestic CM or an Asian DM to fill the Asian slot. If Gurfinkel departs, finding a left-back is essential. It’s also crucial to improve chance creation, deepen striker options, ensure CB depth, and consider the U23 pipeline. Finally, I should scout for potential winter window signings, including free agents and loans from South America.Developing squad strategy and KPIs

I'm considering the network restrictions we face, so I'll suggest some key performance indicators (KPIs) for data analysis, like expected threat (xT), progressive passes, and defensive duel win rates. In the short term, we might need to adjust our tactics during transitions and explore different formations. I should also keep in mind the CSL's salary cap for domestic and foreign players, and create a plan for rotation in cup and league matches. I’ll make an actionable list of target profiles from various leagues, handle contract communications with players like Zhou, and address the future of left-back Gurfinkel.Crafting a concise replacement plan

I'm unsure if Gurfinkel has played in China, but since the user mentioned he might be leaving, it’s clear we need a left-back replacement. I need to follow the guidelines for structuring this plan, so I’ll break it down into three sections: Situation, Priorities, and Moves throughout the window, plus Contract decisions, Risk/rotation, and Timeline. I’ll suggest target profiles with KPIs without naming specific players to avoid misinformation. It could be wise to scout Chinese domestic prospects for left-back positions, but I must be cautious about suggesting players like Liu Yang, considering the feasibility. I’ll write this in Chinese to align with the user’s language preferences.
