Geny Catamo in action for Sporting Lisbon against Celtic (Photo by Carlos Rodrigues/Getty Images)Sunderland reportedly have an interest in the potential transfer of Sporting Lisbon winger Geny Catamo, though his asking price looks too high. According to latest reports, Catamo looked to be worth around €30m back in April, though his asking price is now said to have doubled to around €60m. Catamo looks like a decent talent, but €60m just doesn’t look reasonable, even in this inflated market we’re seeing so far this summer. What next for Geny Catamo to Sunderland transfer saga? Sporting could, in all honesty, do well to cash in on someone who isn’t even one of their most important players.
