Arsenal’s Champions League trip to Porto has heightened security concerns due to the volatile atmosphere surrounding FC Porto‘s upcoming presidential election.

The Mail reports in their Wednesday edition that Portuguese police are on high alert, with increased measures to safeguard Arsenal fans amidst tensions between former Tottenham manager Andre Villas-Boas and the club’s influential Ultras.

FC Porto‘s Ultras, particularly the Super Dragões (Super Dragons) group, hold significant sway within the club. Their passionate, sometimes aggressive support creates an intimidating atmosphere for opposing teams. Ultras groups often have complex relationships with club leadership, and the current election is no exception.

The rivalry between Andre Villas-Boas and incumbent president Jorge Nuno Pinto da Costa reflects a deep divide over Porto’s future. Villas-Boas, the former Porto manager, is seen as a change agent, while 86-year-old da Costa, in power since 1982, embodies tradition and enjoys the Ultras’ backing. This election has become a battleground exceeding typical club politics.

The Ultras’ loyalty to da Costa has put them at odds with Villas-Boas supporters. This led to trouble at the November General Assembly, resulting in the arrest of Ultras leader Fernando Madureira and others. The incident underscores the volatility surrounding the election, casting a shadow over Arsenal‘s visit.

Portuguese authorities are taking no chances. The Mail reports a significantly increased police presence, including officers from multiple units. While Arsenal matches typically have a few UK police present, this fixture could see up to 10 officers deployed as a precaution.
