2005 Liverpool side was a team full of character and resilience. Very good cup side with several leaders who never gave up. They knocked out one of the best Chelsea sides of the last 20 years, that received 15 goals in 38 PL games and finished with 95 points.
Liverpool's road to the final was Juventus, Chelsea, Milan. All tough ties. Both Milan and Juve played a CL final just 1 year before. A really nice underdog story. Not unlike Chelsea of the recent season. They faced much stronger opponents though.
Imo, and this is not nostalgia, the level in CL is dropping. The competition doesn't feel as special as before, and in my mind, the Premier League is becoming the no1 competition to watch atm.
