5 Ronald Koeman (Barcelona 1989-1995) – Another Dutch centre-back to enjoy success at Barcelona, the current Everton manager was hailed as one of the worlds best. Koeman was a crucial component in Johan Cruyffs Dream Team that won four consecutive LaLiga titles from 1991 to 1994. He had superb passing skills, an impressive shot and excellent vision for a team that had passing at its core. He left for Feyenoord in 1995 after winning 10 trophies in total with the Catalan side. Pep Guardiola (Barcelona 1984-2001) – The Manchester City manager originally joined Barcelona as a 13-year-old and, including his time in the youth setup, spent 17 years at the club as a player. After rising through the ranks, Guardiola made his first team debut in 1990 before developing into an impressive defensive midfielder. Was part of the famous Dream Team alongside Koeman and went on to captain the side. He left the club in 2001 for Italian team Brescia and, of course, returned to Barcelona in 2008 to become their most successful manager of all time. 5 5 5 Mauricio Pellegrino [pictured playing for Valencia] (Barcelona 1998-1999) – The new Southampton manager spent almost a decade at his first club Velez Sarsfield before arriving at the Camp Nou on loan in 1998. In doing so he became part of the side, alongside De Boer and Van Gaal, to win the 1999 LaLiga title. That season was to be the Argentineans only campaign for Barcelona as he was then transferred from Velez to Valencia where he won LaLiga on another two occasions in a six-year stay. Frank de Boer played for Barcelona between 1999 and 2003 – Recent managerial appointments means 25 per cent of the bosses are former Barcelona players. Here, talkSPORT looks at them beginning with new Crystal Palace manager Frank de Boer. After a highly successful spell with Ajax the centre-back moved to Barcelona in January 1999 alongside his twin brother Ronald. In doing so they were reunited at the Camp Nou with their former manager in Amsterdam, Louis van Gaal, and went on to win LaLiga that season. However, Van Gaal was sacked in 2000 and Frank tested positive for the banned substance nandrolone a year later. He was suspended for 12 months before UEFA cut the ban short after finding contaminated food supplements were the likely cause for the positive test. He left Barcelona for Galatasaray in 2003. 5 Crystal Palace’s appointment of Frank de Boer as their new manager and Mauricio Pellegrino getting the Southampton job means 25 per cent of the Premier League’s bosses are former Barcelona players.Staggeringly this means there are now more ex-Barca men in the top jobs than there are Englishmen.Before Pellegrino arrived there were three ex-Barcelona players managing – Everton’s Ronald Koeman, Manchester City’s Pep Guardiola and Stoke City’s Mark Hughes.Now two more names have recently been added to take the list to five – beyond the current number of four English bosses in the Premier League.The current managers from these shores are Bournemouth’s Eddie Howe, Swansea’s Paul Clement, Leicester’s Craig Shakespeare and Sean Dyche at Burnley.Brighton manager Chris Hughton was born in London but represented the Republic of Ireland at international level while Hughes and Tony Pulis (both Welsh) add an extra British flavour to the league.Undoubtedly the situation raises a number of questions about English coaches getting a chance at the highest level.Or, perhaps, this means the schooling and education gained at Barcelona is of a more impressive standard – even if you have only been at the club for a limited amount of time.While these questions will linger for plenty of time to come, for now you can scroll through the gallery above to see how the ex-Barca players fared during their time at the Catalan club. Mark Hughes (Barcelona 1986-88) – The Welsh forward is known for his time with Manchester United and Chelsea but the Stoke City manager spent two seasons on the books at Barcelona. Hughes arrived at the Camp Nou from United in 1986, but struggled to find his feet in Spain. He was signed by manager Terry Venables at the same time as Gary Lineker to form a new strike partnership but after scoring just five goals he was loaned to Bayern Munich the following season. Eventually he returned to Manchester United in 1988.
