Squad X11 is a football analysis and match simulation platform built around a database of player and team ratings. It helps fans explore squads, compare clubs, test tactical ideas, and model hypothetical matchups using realistic football data. The platform covers more than 23,890 players, 802 teams, 166 countries, and 42 leagues, with coverage described as spanning 95% of professional football.

Users can build a starting eleven, select formations, assign players to specific roles, and compare team strength across attack, midfield, and defense. The simulator combines ratings, positional fit, role compatibility, and squad balance to estimate win probabilities, expected goals, and possible match events. These simulations are intended for analysis and scenario testing, not as guaranteed real-world predictions.

Squad X11 also offers player and team profiles, league and nation browsing, rating comparisons, and featured or trending player listings. Visitors can explore popular matchups, review squad overalls, and assess how lineup changes may affect a simulated result. The service is designed to make football data accessible for quick comparisons and tactical experimentation.
