Input: Question: Who is the oldest player whose contract expired in early 2011? Passage:In early 2011, the contracts of three young FC Spartak Moscow players (Maksim Grigoryev, Dmitri Malyaka and Yevgeni Filippov) expired, and they decided to switch to FC Rostov. According to Russian football regulations, when a player under 23 years of age who was raised in the club system transfers to a different club after his contract expires, his old club is due compensation from his new club. If the new club plays on the third level (Russian Second Division), the compensation is the player's 5 previous years' salary multiplied by 1, if his new club is in the National League Championship, it's multiplied by 2 and if it's a Russian Premier League club, it's multiplied by 3. The three players signed with a Russian Second Division team FC MITOS Novocherkassk who immediately loaned them to the Russian Premier League team FC Rostov. Spartak lodged a complaint with the Russian Football Union, claiming this was not a fair transfer as the only reason for it was to lower the compensation that FC Rostov was due to pay Spartak. After the protest was declined on 29 March 2011, Grigoryev was registered for FC Rostov and scored a goal on his debut against FC Lokomotiv Moscow on 2 April 2011, the game ended with a score of 1–1. FC Lokomotiv's president, Olga Smorodskaya, filed a complaint with the Russian Football Union and Premier League, claiming Grigoryev was not eligible to be registered and play for FC Rostov. Before the protest was heard, Grigoryev scored a goal in Rostov's 2-1 victory over FC Dynamo Moscow in the 2010–11 Russian Cup quarterfinal. The protest was heard by the RFU's Dispute Resolution Chamber on 21 April 2011. Smorodskaya insisted that FC MITOS did not have the transfer certificate from Spartak in their possession before the transfer deadline and therefore could not have legally registered Grigoryev. The protest was declined as, according to the league, Grigoryev et al. were registered with RFPL before the transfer deadline, even though they were not included on the official rosters on the league's website or in any other sources. The official league website actually still lists the date of their registration as 1 April. In another twist, in January 2012, Lokomotiv signed Grigoryev from FC MITOS. In March 2012, Court of Arbitration for Sport began considering Grigoryev's case. CAS made their decision in May 2012, denying Lokomotiv's appeal.
