Tottenham have reason to be fearful for the long-term future of midfield star Dele Alli after he held formal talks with renowned agent Jorge Mendes, according to reports.

Mendes’ clients famously include both Jose Mourinho and Cristiano Ronaldo, and he has established himself as the go-to man to seal a big move to a European giant. This summer alone, his Gestifute agency helped facilitate the moves of James Rodriguez to Bayern Munich, Diego Costa to Atletico Madrid and Bernardo Silva to Manchester City.
