Tottenham paid super agent Jorge Mendes nearly 37.5% of the fee that brought Matt Doherty to the club – almost four times the going rate.

That is according to finance guru and Football Insider columnist Kieran Maguire, speaking exclusively after this site revealed that Mendes received £6million as part of the £16m deal taking right-back from Wolves to Spurs in the summer.

The 29-year-old signed a four-year contract but is yet to completely nail down a permanent starting XI spot under Jose Mourinho.

And the Republic of Ireland international’s lacklustre form has prompted many to question the value of the transfer.

Maguire explained that Spurs had paid well over the odds to Mendes and that the authorities are attempting to clamp down on such hefty agent fees.

He told Football Insider correspondent Adam Williams: “That’s much, much higher than normal. Normally, you’re looking at 10-15% max.

“There are proposals from Fifa to restrict the amount an agent can take from a particular deal.

“The agents’ trade union is trying to push back on this saying it’s a restriction of trade.

“There is nothing capping agents fees. But from the club’s point of view, Wolves lost 40% of the transfer fee. If it’s embedded into a contract then you’ve got to accept it.”

Through his company Gestifute, Mendes represents the likes of Cristiano Ronaldo, Bernardo Silva and Fabinho.

He also agent to Mourinho and Nuno Espirito Santo, the two managers of  Spurs and Wolves respectively.
