Question: Which of the two athletes Giuseppe Caso replaced is older? Passage 1:In August 2012, he made his European debut for the club, coming on as a substitute in a UEFA Europa League qualifying match against Gomel, replacing Joe Cole in a 0–1 away win. The following week, Sterling scored his first goal for the senior team with a first-half strike in a friendly against Bayer Leverkusen. On 23 August 2012, he started his first match for Liverpool in a Europa League qualifying match away to Hearts in a 0–1 win. He was given his first start in the league three days later in a 2–2 draw at Anfield to Manchester City. He played the full 90 minutes in the loss to Arsenal on 2 September, and the draw with Sunderland on 15 September, where he registered one assist and was named man of the match. On 19 September, Sterling was one of the group of teenagers that travelled to Switzerland to play Young Boys in a UEFA Europa League group match. He replaced Stewart Downing in the second half as Liverpool won 3–5. On 20 October, Sterling scored his first senior competitive goal for Liverpool in the 29th minute in a 1–0 league win against Reading with a strike from the edge of the box. As a result, he became the second-youngest player ever to score in a competitive fixture for Liverpool, behind only Michael Owen.
 Passage 2:In 1991, Makharadze's role was to manage the relations between the federal government and the various regional administrations of Russia, as a member of Boris Yeltsin's team. He was also involved in removing former Communist officials for suspected corruption as the Yeltsin administration's chief inspector, including what was referred to as "nomenklatura privatization." In March 1992 he was appointed as one of the Deputy Prime Ministers in Yeltsin's cabinet, being in charge of managing relations between the regions and the government in Moscow. As part of this, Makharadze and nationality minister Valery Tishkov signed an agreement with the German government to help resettle Volga Germans in their native region. Among his other tasks was to oversee the implementation of economic reforms begun by the central government in the regions. However, when Boris Yeltsin was making concessions to conservative opposition factions in order to gain approval for his economic privatization policies, despite the resignation of Deputy Prime Minister Mikhail Poltoranin it was expected the Makharadze would be forced to resign too. He suggested during this time that a stronger presidential administration was needed. Makharadze was removed from the position of deputy prime minister in December 1992, upon the formation of the new cabinet.
 Passage 3:On 12 July 2019, Caso joined to Serie C club Arezzo on a free-transfer and a 2-year contract. On 11 August he made his debut for the club as a substitute replacing Mattia Rolando in the 53rd minute of a 4–3 away defeat against Crotone in the second round of Coppa Italia. Two weeks later, on 25 August he made his league debut for Arezzo as a substitute replacing Walid Cheddira in the 65th minute of a 3–1 home win over Lecco. On 23 October, Caso played his first match as a starter or Arezzo, a 1–1 away draw against Pro Vercelli, he was replaced by Aniello Cutolo in the 61st minute. Four days later, on 27 October, he scored his first goal for the club in the 63rd minute of a 2–0 home win over Giana Erminio. On 10 November he played his first entire match for the club, a 2–1 home win over Olbia.
