It is highly unlikely that Barcelona will win by a big margin against Inter Milan. Because Inter Milan won the home match. They will want to share the points in away matches. So they will play defensive from the beginning of the match. Moreover, Inter Milan played defensively in the first match as well. They made only 5 shots in the entire match. They were very lucky to be able to win. I think we will see similar gameplay in the second leg. Barcelona will need to attack a lot if they want to beat Inter Milan. Otherwise, Barcelona will not be able to get 3 points against Inter Milan.
After losing to Inter at the San Siro, in this match, Barcelona must score at least two goals. three points is a mandatory result, if Barcelona is to have any chance of qualifying for the UCL knockout stages.
The advantage of playing at home makes Barcelona more free to play, plus now De Jong seems to have recovered from his injury. but what is certain is that Inter will not be easily defeated, they already have points at home, in this match a draw is enough for them.
a tough match for Barcelona, like it or not they have to win the game otherwise that hope will disappear. but for sure, this match will present a match with high tension.
