#6 Claudio Gentile
Claude Gentile wasn't a quintessential number 4 as he also wore a bevy of other jersey numbers during his illustrious playing career in the 70s and 80s.
Nevertheless, the Italian made his name as a no-nonsense, uncompromising, tough-playing defender who was also deployed as a 'sweeper' towards the latter stages of his career. Gentile is arguably one of the finest defenders in the rich annals of Italy and Juventus' history.
Although he was more of a defensive-minded player who sought to break up opposition play, Gentile could also surge forward and provide telling deliveries for teammates in the opposition box.
Often derided as the 'master of the dark arts' for his overly physical style of play, Gentile, along with Dino Zoff, Sergio Brio, Antonio Cabrini and Gaetano Scirea formed one of the most feared defensive quintets for both Italy and Juventus.
#5 Pep Guardiola
Current Manchester City gaffer Pep Guardiola is not only one of the most astute and decorated managers in the game's history, but also a very distinguished player.
Guardiola, who like Gentile did not don the number 4 jersey during the entirety of his playing career, was one of the key components of Johann Cryuff's dream team at Barcelona in the early 90s.
Guardiola was one of the finest midfielders of his generation. The creative, nimble and hard-working player was blessed with a keen ability to read the game and had good positional awareness, tactical intelligence and, of course, passing prowess.
Predominantly deployed as a deep-lying playmaker, Guardiola was part of a brilliant Barcelona team that won four consecutive La Liga titles and the first Champions League title in the club's history.
The Manchester City manager may have scored only 11 times in 382 games for Barcelona, but he was also a potent attacking threat. Guardiola could create chances galore for teammates and possessed a decent shot from distance. However, Guardiola modestly calls himself a 'slow midfielder with no shot and no dribbling'.
Nevertheless, Guardiola's penchant for creativity and ball movement, rather than physicality and pace, inspired a generation of fine ball-playing Spanish midfielders like Xavi Hernandez, Andres Iniesta and Cesc Fabregas, to name a few.
#4 Ronald Koeman
Ronald Koeman is arguably one of the finest goal-scoring defenders to have graced the game.
After making his debut at Groningen, Koeman turned up for Ajax and PSV Eindhoven before arriving at Barcelona for the most prolific spell of his playing career.
One of the key components of Johan Cryuff's dream team, Koeman excelled both in the centre-back and 'sweeper' roles, thanks to his incredible passing range, ball-playing ability and set-piece prowess. His versatility also allowed him to be deployed in a bevy of positions in the middle and defensive thirds of the field.
Koeman racked up an impressive tally of 83 goals in his six-season stay at the Camp Nou, a period that was arguably one of the most illustrious in the club's history as Barcelona bagged four consecutive La Liga titles and the Champions League.
Koeman later embarked on a long managerial career that started with him being an assistant under Louis van Gaal at Barcelona in the 1997-98 season. 20 years later he became the Blaugrana's permanent manager for over a year.
