I have done some research and predict that even though Granada will compete at home in this match, it doesn't mean they have a big chance of winning because if you look at the Head To Head history, it looks like Granada has a chance to end the match in a draw, but that is past and present history. Barcelona's current situation is very different, even a little stronger and I am very confident that Barcelona will appear with a very strong performance.
It doesn't look like Lewandowski is too badly injured and he looks like he will appear in this match but there is no guarantee that Lewandowski will appear in the first half, there is a slight possibility that he will appear in the second half.
Unpredictable based on all your prediction about easily for Barcelona winning over Granada, first half seems excited with Granada lead 2-1 from Barcelona are favorite team for winning this match. Have impressive achievement by Granada on first half with success managed 2-0 before Lamine Yamal score one goals on last minutes of first half. Absent of Robert Lewandowski have bigger problem for Barcelona but left second half and how possibility with Barcelona come back or get loss their three points on away match against Granada.
If loss three points will make Barcelona have gap 4 points behind Real Madrid in current standings La Liga position.
