Tottenham made 'unforgivable' summer mistake that could cost them '£40m' - expert

Keith Wyness criticises Spurs for selling Lankshear to Middlesbrough for £20m without a buy-back clause, warning he could become a £60m player.

Former Everton chief executive Keith Wyness has criticised Tottenham's summer sale of striker Will Lankshear to Middlesbrough, calling the absence of a buy-back clause "unforgivable". Spurs sold the 21-year-old for £20m, but Lankshear has started the Championship season in exceptional form with 13 goals in 13 games as Middlesbrough sit top of the table.

Wyness believes Lankshear could develop into a £50m or £60m player, potentially costing Spurs up to £40m in lost future revenue. He suggested Tottenham were too eager to generate cash for immediate squad improvements under manager Roberto De Zerbi, missing a crucial opportunity to protect their investment with contractual safeguards.
