He was called a few times to play for the national team and had two appearances, first in 2004 against Burkina Faso in a friendly game in Rabat and second in 2009 against Cameroon during the 2010 World Cup Qualifiers in Fez, Morocco.

But after the team had a lot suffered from the left back position especially with the successive injuries of Hicham Mahdoufi, the club decided on 14 June 2011 to sign a two years contract with Zerouali.

The President Mr Abdeslam Hanat said that Raja CA had prepared a flight to take Zakaria Zerouali to Bordeaux, France for a surgery, but the medical staff in Casablanca couldn't allow the player transit because of bad and deteriorating health conditions.

[3] Other physicians would join Hifti arguing that the symptoms exhibited by Zerouali, match a Tropical disease and since these are rare in Morocco, doctors wrongly diagnosed it first as a benign influenza then as food poisoning.

[3] Zakaria Zerouali may have contracted the tropical disease during Raja CA's travels to sub-Saharan Africa for games of the 2011 African Champions League.
