Tottenham Hotspur parted ways with their first-team right-back Kieran Trippier this summer, as the England international was sold to Atletico Madrid for around £20m (Guardian).
This came after the 28-year-old had a pretty dismal season in a Lilywhite shirt, plagued with injuries and inconsistent defending.
The shocking run of form came as a surprise after the defender was one of the shining lights of the Russia World Cup for England, even scoring in the semi-final.
Investment company, Carteret Analytics, believe they have now found the formula for footballers and transfers, and now use their systems to advise top clubs around the country.
In the case of Kieran Trippier, they believe that Tottenham undervalued him extremely. They claim that due to his peak age and value to Atletico, he was actually worth a whopping £61m.
Spurs Web Opinion:
I liked Trippier, but if these guys think Spurs were getting over £60m for him, they need a new formula.
