Liverpool had a great day as they obtained a huge advantage by winning 2-0. But it was not easy for them. Inter did their best and had critical goal chances too. They scored also but it was disallowed due to offside. If Dzeko was a little behind, they would have been 1-0 ahead. And Liverpool were the scoring side finally in the 75th minute. And they scored again in only eight minutes before Inter even reacted to it. We can already consider this draw as finished. Because I see no chance for Inter in Anfield to perform a miracle.
That really was a great game to watch yesterday and in the end i think that Liverpool was not the better team yesterday but simply the more lucky one as for me both teams were completely at the same level yesterday and a 2-0 win for Inter was just as possible as the 2-0 win for Liverpool or a draw. As you already said Inter could have easily been the first team to score as Dzeko was only a little bit offside and after that Calanoglu hit the post with his shot. With the result as it happened yesterday though i think it is pretty safe to say that the chance for Liverpool to advance into the next round are at least 90% now. Inter needs a an early goal in the next game in order to have a chance.
