Step 1: From the sentence, AC Milan’s success in the sixties introduced the ‘libero’ system. This implies statement (A) is correct.
Step 2: A quarter of a century later (late eighties), AC Milan’s success led to the end of the ‘libero’. This confirms (B) is correct — success without the libero.
Step 3: Since ‘libero’ lasted from the sixties till the late eighties (almost 25 years), option (C) is correct.
Step 4: After the late eighties, Italians seldom used a ‘libero’, making (E) correct.
Step 5: The only option not implied is (D). The passage does not say AC Milan was unsuccessful in Europe for that duration. In fact, the opposite is true — they were successful both in the sixties and the late eighties.
\(\boxed{\text{Correct Answer: (D)}}\)
