Police will ramp up security at the Club World Cup after the quarter-final between Tunisia’s Esperance and Al Sadd, of Qatar, was marred by a pitch invasion and outbreaks of violence.

Several fans from the African champions attempted to get on the pitch at the final whistle after the side from Tunis were defeated 2-1 on Sunday, and one Esperance supporter made it to within feet of players and officials.

That an angry fan was able to leap a barrier, evade security and get so close will come as an embarrassment to FIFA in what is one of its most high-profile tournaments of the year.

Police wrestled to the ground several Esperance fans who tried to get onto the pitch, further riling fans who were already irate at what they perceived to be key decisions that had gone against the Africans.

“Following disturbances at the conclusion of Sunday’s match between Al Sadd and Esperance, the security forces inside the stadium acted as quickly as possible to restore order,” FIFA said in a statement yesterday.

Blaming a “minority of supporters”, it said FIFA would increase security for Esperance’s match against Monterrey, of Mexico, tomorrow to decide who finishes the annual intercontinental tournament fifth.

Esperance fans, some of whom appeared to be drunk and out of control, had confronted supporters of the CONCACAF champions outside the Toyota Stadium on Sunday, Mexican journalists at the scene said.

Monterrey later crashed to Japanese champions Kashiwa Reysol on penalties.

FIFA, which said nobody was injured or arrested in the trouble after the game with Asian champions Al Sadd, could also punish Esperance for the behaviour of its fans, several hundred of whom were at the match.

Nabil Maaloul, the coach of African Champions League winners Esperance, apologised afterwards.

“I’m really sorry. Sometimes that happens. Tunisia and Al Sadd are sisters, but of course this should not happen,” he said.
