#2 Inter Milan
They may no longer be mixing it with the greats in the Champions League, but Inter Milan are nonetheless a formidable financial side and have broken the world transfer record on four occasions also. The last time the club did so was in 1999, when they brought in Christian Vieri from Lazio for a whopping £32 million.
Just two years prior to that, they achieved the feat by signing the aforementioned Ronaldo from Barcelona for a then record £19.5 million. An indication of how rapidly finance flourishes in football being that Inter’s fee for Ronaldo was almost doubled by their Vieri record two years later.
Inter also signed Dane Harald Nielsen from Bologna in 1967 for a record £300,000 and their first experience of breaking the record came in 1961 when they signed a Spanish Luis Suarez from Barcelona for just over £150,000.
