"I was surprised how scared Milan were," he told Jutarnji List.
"Tottenham were much, much better and we should have scored more goals, especially in the first half."
Kranjcar has also suggested that Milan will struggle to turn the tie around in north London.
He feels the Rossoneri lack a talismanic match-winner - despite being able to boast the likes of Zlatan Ibrahimovic, Robinho and Alexandre Pato within their ranks.
"If you ask me, the biggest problem for Milan is that they don't have a player who can make a difference," added Kranjcar.
"That is their biggest problem and will make life difficult for them in the second leg."
lol its funny when u hear they dont have players who can make the difference and we are searching the whole season for a striker who can make a difference and they have pato, ibrahimovic , robinho.....
