The Lilywhites appeared to be on the brink of a famous win at the San Siro on Tuesday night after Christian Eriksen gave Spurs a first-half lead against Inter Milan.
However, Argentina international Mauro Icardi scored a brilliant equaliser in the 85th minute to rescue a point for Luciano Spaletti’s side at home.

Spurs lost 2-1 to Watford in their final Premier League game before the international break despite an impressive 3-0 victory at Manchester United back in August.

Brighton have already beaten Manchester United at the Amex Stadium this season.
Former Arsenal midfielder Merson is tipping Brighton to secure a point against Tottenham on the coast this weekend.
“I don’t know what’s happened with Tottenham,” Merson told Sky Sports.
“They played well against Inter Milan and then lost the game – they’ve probably played worse this season and won.
“They are stuck in a rut and need something from this game. I don’t care who you are but you cannot turn that run of form around in an instant, especially when you consider Brighton at home are a completely different prospect.”
Merson added: “Chris Hughton must pull his hair out at the difference between his side’s form at home and away, but they fought back last week when they looked out of the game at Southampton. Spurs have played well in games and still lost, after a while that takes its toll.”
Tottenham finished in third place in the Premier League table behind defending champions Manchester City and Manchester United.
