Question: Which former italian professional footballer, born in 1970, participated in the 1999–2000 FA Cup Final between Chelsea and Aston Villa?
Context: The 1913 FA Cup Final was contested by Aston Villa and Sunderland on 19 April 1913 at London's Crystal Palace.  Playing as the home side, Aston Villa won 1–0 on a goal by Tommy Barber on a crossed ball from Charlie Wallace.  Wallace had earlier missed a penalty, something that would not occur again in FA Cup play until the 1988 final between Wimbledon and Liverpool. The Aston Villa Under-23, formerly Aston Villa Under-21 and Aston Villa Reserves, are the most senior youth development team of Aston Villa and compete in Premier League 2 (Division 2) of the Professional Development League and the Premier League International Cup in the 2016–17 season.  The team were part of the FA Premier Reserve League since its foundation in 1999 and were winners of the 2011-12 Premier Reserve League South title, the last in that format.  The team plays its home games at Villa Park and Bescot Stadium (home of Walsall F.C.).  Aston Villa also have an academy side that competes in the Under-18 division of the Professional Development League and the FA Youth Cup annually. The 2000 FA Charity Shield (also known as the One 2 One FA Charity Shield for sponsorship reasons) was the 78th FA Charity Shield, an annual football match played between the winners of the previous season's Premier League and FA Cup competitions.  The match was played between Manchester United, who won the 1999–2000 Premier League, and Chelsea, who won the 1999–2000 FA Cup, and resulted in a 2–0 Chelsea win.  The goals were scored by Jimmy Floyd Hasselbaink and Mario Melchiot.  Roy Keane was sent off for a challenge on Gustavo Poyet and was the last person to be sent off at the old Wembley Stadium. Robert Chatt (August 1870 – c.1955) was an English footballer who was a member of the Aston Villa team which won the Football League championship three times in the 1890s.  Chatt was credited with scoring the fastest goal in FA Cup Final history, scored after just 30 seconds in the 1895 FA Cup Final.  This record stood for 114 years until Louis Saha of Everton scored after 25 seconds against Chelsea in the 2009 final. Roberto Di Matteo (] ; born 29 May 1970) is an Italian former professional footballer and manager. The 1895 FA Cup Final was contested by Aston Villa and West Bromwich Albion at Crystal Palace.  Aston Villa won 1–0, with Bob Chatt being credited with scoring the fastest goal in FA Cup Final history, scored after just 30 seconds.  This record would stand for 114 years before being broken by Louis Saha of Everton in the 2009 FA Cup Final with a goal after 25 seconds. The 1994 Football League Cup Final took place on 27 March 1994 at the old Wembley Stadium.  It was contested between Manchester United and Aston Villa.  Aston Villa won 3–1, with one goal from Dalian Atkinson and two from Dean Saunders, to claim their fourth League Cup final victory; Manchester United's goal was scored by Mark Hughes, before Andrei Kanchelskis was sent off for handball.  Manchester United would go on to win both the Premier League and FA Cup that season, the result denying United a domestic treble, while Villa finished 10th in the Premier League. The 2000 FA Cup Final was the 119th final of the FA Cup, and the 72nd (excluding replays) and last to be played at the old Wembley Stadium.  It took place on 20 May 2000 and was contested between Chelsea and Aston Villa, the latter making its first FA Cup Final appearance since winning it in 1957. The 1999–2000 FA Cup was the 119th staging of the world's oldest cup competition, the Football Association Cup or FA Cup.  Both the semi-finals and final of the competition were played at Wembley Stadium for the last time before reconstruction work began.  The competition culminated with the FA Cup Final between Chelsea and Aston Villa.  The game was won by a goal from Chelsea's Roberto Di Matteo, giving them a 1-0 victory. Sunderland Association Football Club was founded in 1879 as Sunderland & District Teachers Association Football Club by James Allan.  They turned professional in 1885.  Sunderland won their first Football League championship in the 1891–92 season two years after joining the league.  They won the next Football League First Division on three occasions in four seasons; in 1892, 1893 and 1895, separated by a runner-up spot in 1894.  In the 1901–02 season, Sunderland won their fifth Football League First Division championship.  They came close to completing the "league and cup double" in the 1912–13 season, winning the league but losing to Aston Villa in the 1913 FA Cup Final.  The team's next success came in the 1935–36 season when they won the League Championship and also the Charity Shield.  They had not won the FA Cup until the 1936–37 season when they defeated Preston North End in the 1937 FA Cup Final.  Sunderland entered The Football League in 1890 and were not relegated from the top division until the 1957–58 season; a total of 58 seasons in the highest division of England.  Their next trophy came in the 1973 FA Cup Final as they beat Leeds United 1–0.  They reached the 1985 Football League Cup Final but finished as runners-up to Norwich City after being beaten 1–0.  In the 1986–87 season Sunderland were relegated to the Football League Third Division for the first time in their history under the management of Lawrie McMenemy, they however, returned to the second division the following season as champions–their lowest position in the English football league system.  Their first appearance in the Premier League came in the 1999–2000 season after being promoted as champions from Division One.  In winning promotion the club gained 105 points, which was a record at the time.  Sunderland gained just 15 points in the 2005-06 season, which set the record for the lowest number of points in a Premier League season, which has since been eclipsed by Derby County.
