It seems that Xavi will use De Jong as replacement for Lewandowski if he cannot recover and play in the match against Real Madrid but De Jong is also playing after recovering from his injury so Xavi has to really consider everything so that nothing bad happens to his players.
However on the other hand some of the latest news also states that Lewandowski can recover on time and can even take part in El Clasico and this is good news even though it is not necessarily true.
But despite all the rumors that have been circulating it seems that Xavi knows more about the Barcelona squad so he can have better plan to be able to perform optimally in El Clasico.
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.
