2002-05 Juan Román Riquelme came under contract with Barcelona in 2002. The Argentine had established himself with Boca, but wanted to leave due to personal reasons: a brother was kidnapped, but set free. When Barca signed Ronaldinho, it put them over the roster limit for non-Spaniards. Riquelme was transferred on loan to Villarreal to make way for the Brazilian great.
