I'd say Pirlo, Barzagli and Tevez were pretty solid "older players"
And we havent seen the last of Evra, who's improving.
Actually, apart from the panic buy Toni, when our entire frontline was severely injured +amauri, i cant recall us buying an older player that didnt do what we expected.
Dont say Lucio. We got him as a 4th centreback, and he left cause he forgot how little the 4th centreback plays
