Netherlands defender Stefan de Vrij has told reporters he will join Inter on a five-year deal when his contract with Lazio expires at the end of June.
The 26-year-old defender has been heavily linked with a switch to San Siro for a number of months, meaning his involvement in the last-day drama between the sides in Serie A came at an unfortunate time.
With Lazio leading 2-1 and needing only a draw to qualify for the Champions League at Inter's expense, De Vrij fouled Mauro Icardi in the area and the Argentin striker converted the resulting penalty.
