It is important for Lukaku to be the savior in this important game. This can help him find more chances in the starting eleven.
To be honest the game between porto against inter was having a high tension. Both were equal and very competitive to make goals but the red card has become a very big problem for porto. I think that it will be draw if porto was not getting red card.
The red card was just giving lukaku a chance to play even freely and goal happened after red card has been given. That proves that how big the impact from the red card.
it's unnecessary thing by porto's player but so far that's a really good game. The performance of clubs are so good even though it's ended with small scores for inter as a winner from the match.
