First half, It was pretty even with no clear chances, until the last minutes of the first half where Inter pressured for a couple of minutes and could've scored. Udinese had some nice build up but no clear chances IIRC.
At the half Ranieri replaced Alvarez with Nagatomo

Inter were more compact defensively but clueless upfront and with the game going, Inter started to open up, and udines used that and Isla scored and could've scored again but Di Natale missed the penalty.
