I do not agree with Ahmad's conclusion there:

"Based on above I think the right word is (Bull)."

A torero is by no mean a 'Bull'!
Torero is bullfighter, a human being. A high-rank torero is called Matador.

The Spanish Matador الماتادور الإسباني is very well used as a nickname for the Spanish soccer team. This is mere variation by some savvy writer.

"A torero (roughly "bull handler") is the main performer in bullfighting events in Spain and other Spanish-speaking countries. He or she is the person who performs with and finally kills the bull. The role is also called toreador in English (and in Bizet's opera Carmen), but this term is almost never used in Spain or in Latin America. The term torero encompases bullfighters who fight the bull on foot as well as those who do so on horseback (picadores and rejoneadores)

The most skillful toreros can be elevated to the title Matador at an special bullfight called an alternativa. At this bullfight the Novillero (junior bullfighter) is presented to the crowd as a matador de toros."

The text suggests that the Tunisians were able to tame even the bull-tamer--a hint for the capablity of the Tunisian team players to stand against such powerful, professional team, i.e. Spain.
