Question: Who is the oldest player whose contract expired in early 2011? Passage 1: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.
 Passage 2:A military flying school was set up at the site of the present-day RAAF base on 28 August 1916, when the area was known as Ham Common. RAAF Station Richmond was established on 30 June 1925 as the fledgling service's first air base outside Victoria. Its initial flying unit was No. 3 (Army Cooperation) Squadron, operating Airco DH.9 light bombers and Royal Aircraft Factory S.E.5 fighters, and for the next decade the commanding officer of No. 3 Squadron was also in charge of the base. Among these were Squadron Leaders Frank Lukis (1925–30), Harry Cobby (1930–31), and Bill Bostock (1931–33). Headquarters RAAF Station Richmond was formed as a separate entity on 20 April 1936, under the command of Group Captain Adrian "King" Cole. Other units, including No. 22 Squadron flying Hawker Demons, and No. 2 Aircraft Depot, had been established in the preceding months. No. 4 (General Reconnaissance) Squadron was formed in May 1937, followed by No. 6 (General Reconnaissance) Squadron in March 1939. Two Fleet Cooperation units were also established, No. 5 Squadron in April 1936 and No. 9 Squadron in January 1939. No. 23 (General Purpose) Squadron formed in February 1939. As well as an Air Force base, in its pre-war days Richmond was used as a supplementary airport for Sydney; various aviation pioneers employed it in the 1930s, including Charles Kingsford Smith and Jean Batten.
 Passage 3:The Indian Squads were announced on 13 February. Dhawal Kulkarni got his maiden call up to the national squad, having been selected for the test squad after a strong debut Ranji trophy season where he was the highest wicket taker. L Balaji made a return to the Test squad after a five-year hiatus having last played in a test in 2004. Balaji was dropped from the ODI squad after he played in a single match in the previous tour, he was replaced by the now fit Munaf Patel. In the test squad Balaji replaced Pragyan Ojha with the selectors opting for an extra seamer instead of an extra spinner for the tour. Ojha retained his place in the ODI and T20 squads. Subramaniam Badrinath was dropped from the test squad in favour of reserve Wicket-Keeper Dinesh Karthik after Karthik too had a strong Ranji trophy season. Karthik was selected for all three squads, replacing Jadeja in the ODI squad. Ravindra Jadeja's impressive ODI debut was rewarded with a call up to the Twenty20 squad but Jadeja will be replaced by Sachin Tendulkar for the subsequent ODI series. Munaf Patel made a return to all three squads after having to pull out midway through the previous tour of Sri Lanka due to injury. Harbhajan Singh also made a return to all three squads after having to pull out at the beginning of the previous tour to Sri Lanka due to injury.
