Really? So ignoring the fact that anyone who is under 30 is still in their prime and likely wont be here in 3 years ANYWAY... Messi is 30, Lewandowski is 29, Suarez is 30, Bale will be turning 29 this year, Aguero is 29, and they are in the prime of their career and you would take them in a heartbeat.
Rooney 33 this year
Jagielka 36 this year
Williams 34 this year
Baines 34 this year
Coleman 30 this year
So out of as quad of roughly 30 players, that leaves us with Jagielka who will be gone in the summer, Williams who will likely be gone in the summer, and Baines who will be a backup in the summer, leaving only 1 likely starter in Coleman and a part-time starter in Rooney for next season. Thats pretty good.
