Van Nisterlooy was 24, Xavi 25, Alan Shearer 22, Del Piero 24, Jagielka 27, Arteta 27. I think Walcott had the same injury one year ago and today is his first game after the injury. Was good at the start of the match but because i was posting that i wasn't watching the game closely in last half an hour.
Baggio was 18 and again at the age of 34. This part of the wikipedia is surprised me about Baggio: "At the start of
2001–02 season, he scored eight goals in the first nine games, leading him to the top of the Serie A goalscoring table, and forming a formidable offensive partnership with
Luca Toni. Unfortunately, during that season, he tore the
anterior cruciate ligament and
meniscus in his left knee twice, a serious injury which put his chances of playing at the upcoming World Cup in jeopardy. Despite this severe injury, he came back three games before the end of the season, making a record recovery of 76 days.".
Falcao was 27 nearing his 28 birthday in february (he injuried in january). So he was a little older but not to much. He will be 29 next month so time is not on his side and he must find his form back quickly.
