I think if Lukaku hadn't been on the field, Inter would have had an opportunity to score... Although he was able to create some moments, he didn't manage to score... But he also prevented the ball from being sent into the target a few times... In the final minutes Inter showed very good class and Man City could do nothing with those dangerous attacks, but with the realization of the moments was a problem...
Inter Milan would have all the opportunity to get at least a goal in that match but trees and lack of finishing denied them clear opportunities to take the game to an extra time. Both Martinez and Lukaku wasted a lot of opportunities. There was a clear chance for Martinez to pass to Lukaku which would have given them a goal but he decided to score alone, while Lukaku's lack of coordination and right positioning deprived this great team of the opportunity to give Italy a European title this season. Maybe the Belgian might have to return to Chelsea but Inter can keep him for another season because he had a fairly good season. But a goal in the finals would have been the needed catalyst to give him a permanent deal at Inter.
Inter Milan performed far beyond my expectation because I expected Manchester City to dominate the match from beginning to end and thought the goal will be up to three as they did to Real Madrid. But coach Inter coach Simone Inzaghi showed some good technical soundness that slightly outsmarted City.
