Anyways, the first game for Liverpool is against Milan. It is at San Siro. What is your opinion?

I think Liverpool will start with a victory. Milan won their last league game but still it doesn't change the fact that they are unbalanced these days.
The match between Milan and Liverpool will be a very competitive one given the recent performances of both teams. Milan have been going through an up and down period lately. Although they are very effective in attack, they have problems in defense. Fonseca is not playing the way he wants to play at Milan at the moment. Milan's signings this season have not performed as expected and there is a negative atmosphere in the team. Liverpool, on the other hand, is a very strong team in terms of offense even though they lost their last games. For this reason, Liverpool's effective attacking players are likely to take advantage of Milan's defensive deficiencies. I expect an exciting game where both teams will score, so I expect both teams to score. A draw might be a good option.
