West Brom have the oldest team in the Premier League – and West Ham has the fifth youngest team on average.

The season started with a youthful air in September when Reece Oxford gave an assured performance in a West Ham shirt against Arsenal.

At 16 years and 237 days, he became the second-youngest player to start a Premier League game – and finished with the best pass percentage in the match of 95%.

He made his debut for West Ham against FC Lusitans aged 16 years and 198 days, making him the club's youngest ever player, beating a record of 16 years and 221 days set in 1922 by Billy Williams.

In contrasts, the average age of West Brom players fielded this season has been 29.2 years old according to figures released by the CIES Football Observatory.

That’s older than others vying for the title of oldest squad – Manchester City (28.5 years), Bournemouth (28.4) and Watford (28.3).

In fact, West Brom’s average is the third highest of any team in Europe’s “big five” leagues – England, France, Germany, Italy and Spain.

Tottenham have been fielding the youngest players in the Premier League. The average Spurs player has been just 24.7 years old this season.

Liverpool have been the next youngest (25.5 years) followed by Newcastle (25.6), Manchester United (26.4), West Ham (26.4) and Aston Villa (26.6).

As for Oxford, his profile has diminished lately, making some appearances in the squad. Controversially, he was blocked from attending October's Under 17s World Cup with manager Slaven Bilic fearing "burn-out".
