World Cup 2018: 10 Footballers Who Will Probably Be Playing Their Last World Cup 

#7 Tim Cahill (Australia)

Australian Socceroos Training Session

Talk about a veteran. Tim Cahill, the 38-year-old ex-Everton star was announced as part of the Australian squad this past week and frankly, it's not really that much of a surprise.

Cahill has been the star of the Australian squad for years, and while it is unlikely that the Socceroos will come away with anything other than a token victory, Cahill will be hoping he can help mount a challenge for the round of 16 against group rivals Denmark and Peru.

Cahill spent the second half of this season back at Millwall, in the Championship, and was released by the club at the end of the season. Cahill has continued to defy the years though, and there is every chance he may spend one last year in Australia before officially announcing his retirement from football.
