Alex Song (Cameroon)
The Cameroonian international's football career can be divided into two parts, his time before joining Barcelona and the time after it. Alex Song was one of the influential figures in Arsene Wenger's side during his seven-year stint with the Gunners before moving to Barcelona in 2012.
The midfielder made his debut just nine days after signing for the club against arch-rivals Real Madrid in the 2012 Spanish Super Cup but soon found himself more on the bench. The Cameroonian unsurprisingly failed to break into a midfield that contained Xavi, Iniesta, and Busquets.
In four seasons as a Barcelona player Song made 65 appearances and scored once before spending the last two years of his Barcelona contract on loan to West Ham United. The midfielder won the Spanish Super Cup and La Liga during his stay at the Nou Camp before joining Russian side Rubin Kazan in 2016.
Alex Song is now seen plying his trade with Swiss Super League side Sion.
Yaya Toure (Ivory Coast)
The Ivory Coast midfielder joined Barcelona in 2007 for a reported fee of €10 million following an impressive spell with AS Monaco. He spent three seasons with the Spanish giants before moving to the Premier League to join Manchester City in 2010.
After an impressive first season, Toure found himself out-of-favour with a young Pep Guardiola in his first season with the club, after the Spaniard opted for Sergio Busquets ahead of the Ivory Coast international. The sour relationship with Guardiola eventually led to Toure's departure from the Catalonian capital in 2010.
The midfielder enjoyed a trophy-laden three seasons with Barcelona and was part of the side that won the treble under Pep Guardiola in 2009. The midfielder left the club after making 118 appearances and scoring 6 times for the Catalonian giants.
