I'd tend to agree if there haven't been 20 odd transfers in the last few years alone that have been over 70 million euros. Additionally, I think the success rate of those players are probably very similar to the success rate of spending lots of money on 18 years old that haven't yet made a handful of senior appearances for their club
If you look at those transfers though, a fair chunk haven't been successful and a decent percentage have been total disasters! We can't lose sight of just how much money £100m is in the 'real' world i.e. what that could buy in terms of infrastructure (academy/stadium) and how many season tickets/replica shirts that is.
Here is a list of the world's most expensive transfers, how many clubs do you think will be completely happy with their outlay?
Neymar - £200m - Good player, hasn't delivered a Champions League. Qualified success.
Mbappe - £200m - Good players, bags of potential, £200m could look like value if broken down over 10yrs or they re-sell for a large sum. Still, no CL. Qualified success
Countinho - £145m - Disaster.
Joao Felix - £126m - Has he done much since joining? Certainly hasn't looked a £126m player yet....
Griezmann - £120m - Disaster
Dembele - £105m - Disaster
Pogba - £90m - Disaster. Hasn't delivered on the pitch, caused a headache for two managers now...nobody knows how or where to play him.
Hazard - £90m - Disaster.
Ronaldo - £90m. Huge success...but that £90m was 10yrs ago...so would be £200m+ now.
Bale - £90m. Qualified success.
Gonzalo Higuaín - £75m - Hit and miss, arguably overpriced.
Maguire - £75m - Far too much money to pay. Looking more miss than hit
Van Dijk - £75m - Unqualified success
Suarez - £75m - Qualified success
Kepa - £75m - Disaster
Pepe - £75m - Wouldn't say disaster but a LOT to prove
Lucas Hernandez - £75m - Doesn't get in the side....hard to say disaster but doesn't play!
More misses than hits amongst that lot in my opinion!
