Yes. The compare tool takes any two tracked players regardless of club, and any two tracked clubs. The club page has its own comparison that takes up to four members of the same club, useful for settling positions inside your squad.

A stat divided by the minutes actually played and scaled to one full match of 90 minutes. It removes playing time from the comparison, so a player with 20 appearances and one with 300 are judged on what they produce per match rather than on totals. Over very few matches it is still noisy, so check the sample size shown next to it.

The share of tracked players a value beats in the same stat. A percentile of 90 for assists means the player has more assists per 90 than 90 percent of the pool. Percentiles let you compare stats measured on different scales, such as goals and average rating, on one radar chart.

Because the data behind it moves. Club info and overall stats are refreshed about every 30 minutes and members and matches about every 6 hours, and percentiles shift as the whole pool plays more. A comparison is a snapshot of the season so far, not a fixed result.
