I love the discussion of great sides and eras. The Rise and the Fall they make great stories - I digress
To get the era right - it's the end of Benfica's era, the clashes with the Ye Ye team, the heroic slain would be saviours of European football Shankly's Liverpool, the machinations of fixer Italo Allodi, the methods of task master Herrera and the giant, Inter, finally being slayed by the heroes - Celtic's Lisbon Lions and a vengeful rejected Inter son Di Giacomo scoring the goal that would break inter's dominance of Serie A.
I agree it should be wider but only up to 1967 to capture the team at it's peak just before the fall. Herrera was gone to Roma by 1969. 63 is a good start as it is the year they won Seria A for the 1st time under Herrera and the season he changed his formation having come second in 62. Take it to 1967, as they won the Scudetto again in 65 and 66 despite being beaten by Real Madrid's "Ye Ye" team
in the semis of the European Cup in 1966 and being beaten by Celtic in 1967 European Cup Final they were clearly still a force in European and Domestic Football.
Domestically after 1967 they were finished though. The 1966-67 season Inter set a record of 7 straight victories, and by April were 4 poins clear of Juve, they however started to disintergrate that same year with two matches of their season left against Celtic in the European Cup final and Mantova in the league they lost both. The intense preparation, isololation and sheer pressure cooker of being in Herrera's side had got to them.
The team cylce was nearing it's end. Herrera had fallen out with club officials, Suarez was rumoured to be heading back to Spain and Moratti the owner was keen to give up the presidency. End of an era? In 1967 looks so. Celtic's attacking football in the 1967 European Cup final had destroyed the Inter myth and the system on the continent at least. Just as Inter's football had succeded the attacking 4-2-4 approach of the Benfica era,
so their version of catenaccio -widely copied in Italy - would be succeeded by Total Football
In 1967-1968 Inter finished 5th, but by then Guarneri and Picci were gone and Jair had left at the end of 1966-1967 season. Herrera would leave for Roma by 1969. So although Herrera's era is 1960-1968, his tactical switch happened in 1963 season and by end of 1967 three of the players that made it so succesful were gone, Picci, Guarneri and Jair.
