This should have been a concern for Xavi since last summer's transfer, the need for an additional striker to replace Lewandowski when he is injured or absent for other reasons, so that there are no problems when facing important matches, obviously it will be detrimental to Barcelona if in the end the result of the match will disappoint all fans. and experience unnecessary defeat.
It is clear that the Laliga competition this season is very interesting so that Barcelona can continue to be on the winning track, at least they have sharp attack power in their front line, without Lewandowski it might have a little influence on the result of the match, but this is Xavi's task and challenge, he must show that he can overcome this problem and fielded all the players he had to get the full three points.
We know there is not much Barcelona can do in the transfer market because the financial problems they are facing mean they have to comply with every direction from Laliga, so it's not that Barcelona doesn't want to add a striker but there are things preventing them from doing that. So far Barcelona is still playing quite well, and Lewandowski's injury might make them have a little difficulty in scoring goals, but seeing how Xavi Hernandez handles every difficulty that occurs, I think this time Xavi will be able to handle it well. Another Barcelona player could very well cover the gap in Lewandowski's absence, and Xavi knows exactly who that player is.
