Ajax coach Frank de Boer admits Jan Vertonghen could sign for Tottenham today.

De Boer admits Vertonghen is now waiting on the 'green light' to make a move to the Premier League.

Taking that into account, he left the 25-year-old out of his squad for a pre-season exhibition game against FC Emmen.

"John has his head in London, so we sent him home," De Boer told Telesport.

"He is only waiting on a few minor details before he gets the green light."
