There are plenty of great options: Giggs, Scholes, Baresi, Maldini, Facchetti, Puyol, etc.
For me though, the greatest is Francesco Totti. The others above played for clubs who won multiple trophies, and all won the champions league at least once. Aside from a smattering of Coppa Italias and one Scudetto, Totti didn’t win anything with Rome.
For me, it’s easier for a top player to stay at a top club, rather than be a top player like Totti and stay at a club that was rarely considered the best in Serie A. For my money, he is the greatest one-club man of all time.
Who would you choose?
I’ll mention Jamie Carragher then as nobody else has.
I mean, it’s not him but he should be mentioned. Starred in the shittest Liverpool team to ever win a Champions League, also won the UEFA cup, two FA Cups, three League Cups, two Super Cups, two Community Shields. Played for Liverpool for 17 years despite growing up an Everton supporter.
Moreso than Gerrard? Are we now not calling Gerrard a one-club man because of that short stint in the MLS?
He played for two clubs, rules him out
Playing for two clubs tends to rule you out of being a one-club player
Yes… thats literally why
You answered your own question. Remarkable.
