MOSCOW, May 18 (RIA Novosti) - Russia's Federal Security Service (FSB) said on Sunday it was prepared to provide anti-terrorist security at the Champions League final in Moscow on May 21.

The all-English Champions League final will see Britain's Manchester United and Chelsea playing against each other. Thousands of British soccer fans are expected to attend the final in Moscow.

"We are participating in all measures to provide security. Our main task as part of the work with arriving soccer fans will be to track down those who are possibly on the wanted list and are involved in international terrorist organizations. We will not let these people in," FSB said.

Russia's President Dmitry Medvedev signed an order on May 14 allowing Manchester United and Chelsea fans holding tickets for the final at Luzhniki Stadium to enter the country without visas.
