That again is a hyperbolic opinion based mixture of wishful thinking and outright nonsense. Were are the actual facts ? Where is this historical data that you speak of ? Any chance you show your working ? Links articles etc. you obviously have them at your fingertips as you readily quote them at every opportunity. Would genuinely be interested as its not something I am familiar with.
Ok lets look at the players I used originally.
Thierry Henry - Over twenty league goals a season from the age (at start of season) 24-28. Never once did he repeat that feat, not even in America.
Andy Cole - His last good season was he was 28.
Wayne Rooney - Not quite the same but we can still see the last good season was when he was 28, he was stil a top level operator but could no longer cut it up front, so had to be moved futher back.
Owen - Im sure well know about his regression, can scarcely be arsed to look it up. Just done, his 24yo season was never bettered.
Hasselbaink - Tbf he had a good 29yo season, never bettered after that, steep decline.
Anelka - Finished by the age of 26 really.
Sheringham - One of his best ever season at 34. Albeit in the championship.
Bergkamp - Still going strong well into his 30s.
RVP - Best ever seasons 28 and 29, an unfortunate injury after that.
Shearer - Over 20 league goals at 34.
If you need more then let me know. Thank you.
