Inter Milan captain Lautaro Martinez admits they leave Real Sociedad frustrated after last night's 1-1 draw.
Lautaro struck late on to earn a point in their opening Champions League group game.
He later said: No, because we didn't do what we had prepared. We struggled and there's a lot to improve
We faced a team that pressed high, we were not good enough at attacking the space, we were always offside and when you face these sorts of teams it's always hard. It happened in the derby too sometimes, so we have to work on this."
He added: "We knew they were a strong side and many teams have struggled against them.
The stadium is small but the fans are close. It was important not to lose otherwise it would have been difficult, it's important to return home with one point."
