It appears that Ghanaian international Michael Essien will be absent from the Real Madrid squad for the 13th day of La Liga due to an allergy to a pharmaceutical product. Essien has reportedly refused the selection for the upcoming match against Betis in Seville not because of injury but due to convalescence from an allergic reaction to a medication earlier in the week.
The information suggests that Essien will be unavailable for a few days as he recovers from the allergic reaction. This absence is notable, and it adds to the team’s considerations as they prepare for the match without the services of the experienced midfielder.
