Of the many parameters used to gauge the health of a team, age is an important criterion. If the team is relatively young, supporters and management generally have more patience when it comes to results. Arsenal supporters, therefore, have every reason to wait for success as the Gunners have the youngest squad so far in this season of the Premier League. According to data from the Swiss-based CIES Football Observatory, Mikel Arteta's team not only have the lowest average age among teams in the league (25.01 years), but 11 per cent of their total minutes played have featured under 21 players. Across Europe, Monaco have the youngest line-up among major leagues with an average age of 24.3 years, while Bayer Leverkusen fielded U21 players for the most minutes at 24 per cent.
