Cesar Luis Menotti and Carlos Bilardo are the coaches who steered the Argentina to victory at the 1978 and 1986 FIFA World Cups™ respectively. The two supremos could hardly have had more different styles, and it can almost be said that since their successes, every other coach has been put in one of two camps - the Menottista, who see technique as the focal point of the game, and the Bilardista, who see it more as a question of the right tactics.
There is of course a little more to it than that. Here, FIFA.com takes a look at the 1978 and 1986 world champions who swapped their boots for a clipboard and tracksuit.
The Argentina 1978 winners
The two big names from this team to have taken up the coaching reins are Daniel Passarella and Americo Ruben Gallego, and they began their new careers side by side at the legendary River Plate club, where they had previously plied their trade as players. Passarella became head coach in the early 1990s with Gallego as his assistant, and the pair went on to win three league titles.
This success saw Passarella named as national team coach, steering Argentina to a silver medal at the Men's Olympic Football Tournament Atlanta 1996 and to the quarter-finals of France 1998. He then went on to manage teams in Italy (Parma), Mexico (Monterrey) and Brazil (Corinthians) before taking over at River again.
Gallego, meanwhile, went on to establish an enviable record as a head coach, guiding four different teams to league titles. In 1994, he took over from Passarella at River, with the club going undefeated to win the Apertura (opening tournament). The following year, he became Passarella's assistant in the Argentina set-up before returning to River in 2000 and winning the Clausura (closing tournament). He then repeated the feat with Newell's Old Boys in 2002 and Independiente two years later, before taking Toluca to the Mexican title in his first season in charge in 2005.
Another little-used member of the Argentina 1978 squad moved into coaching, namely third-choice keeper Ricardo La Volpe. He cut his managerial teeth in Mexico at no fewer than nine clubs, winning the league in 1993 with Atlante. His unusual style and excellent results saw him made Mexican national team coach, where during his four years in charge (2002-2006) he won the Gold Cup and reached the Round of 16 at Germany 2006. He then returned to his native Argentina to coach Boca Juniors and Velez Sarsfield in 2006 and 2007 respectively, although he is yet to win a title in his homeland.
Ubaldo Matildo Fillol is another goalkeeper to have tried his hand at coaching. After a brief stint in charge of Racing Club, the man who kept goal for the Albiceleste throughout the 1978 FIFA World Cup was brought in by the Argentinean federation to look after the U-15 team and then the goalkeepers. In 2006, he was part of the backroom staff at the FIFA World Cup in Germany.
Other 1978 heroes who have tried their hand at coaching, either in Argentina or abroad and with varying degrees of success, include Omar Larrosa, Leopoldo Jacinto Luque, Jorge Olguin, Daniel Valencia and the former Tottenham Hotspur duo of Ossie Ardiles and Ricky Villa.
The Mexico 1986 winner
Three big names stand out here: Diego Maradona, Jorge Valdano and Nery Pumpido, who all played under Menotti at Spain 1982 then went on to win football's greatest prize under Bilardo four years later. The most Menottista of the three is undoubtedly Valdano. His coaching career was carried out entirely in Spain, first at Tenerife, then Real Madrid, with whom he won La Liga in 1995, and finally Valencia before he retired in 1997.
Pumpido, on the other hand, is a definite disciple of Bilardo. The former goalkeeper began coaching at second division outfit Union de Santa Fe before tasting success in Paraguay when he steered Olimpia to the 2002 Copa Libertadores. Further stops in Mexico (Tigres and Veracruz) and Argentina (Newell's Old Boys) failed to bring any more success, however.
And then in between the two, you have Maradona. El Pibe de Oro chose to borrow from both Menotti and Bilardo, but this did not prove to be a winning formula, either with Mandiyu de Corrientes in 1994 or Racing Club the following year. The former midfield genius nevertheless still harbours hopes of coaching his beloved Boca Juniors and perhaps one day the Albiceleste.
Another talented player from Mexico 1986 has had more success since stepping over the other side of the touchline. Claudio Borghi began his coaching in Chile at Audax Italiano before managing a number of amateur sides. In a move which came as quite a surprise to most observers, he was named head coach of Colo Colo in 2006, but he proved the critics wrong by helping his side to become the first quadruple champions, winning the Apertura and Clausura in 2006 and 2007.
Two 1986 winners are currently part of the national set-up working with Argentinean youth players, namely Sergio Batista and Jose Luis Brown. The former began his managerial career in Uruguay and, unlike Brown, has coached in the top flight, at Argentinos Juniors and Talleres de Cordoba. Batista is currently in charge of the U-20s, while Brown, having coached in the lower leagues, looks after the U-17s.
Oscar Ruggeri and Jorge Luis Burruchaga are two other 1986 FIFA World Cup winners who have tried their hand at coaching. Defender Ruggeri has managed teams in Argentina (San Lorenzo and Independiente), Mexico (Chivas, Tecos America) and Spain (Elche), without winning any titles. Burru, who scored the winner against West Germany in the 1986 Final, began coaching in the Argentinean second division with Arsenal, whom he steered to promotion before taking over at Estudiantes de La Plata and then Independiente.
Oscar Garre, Ricardo Bochini, Nestor Clausen and Luis Islas have also gone into coaching but with no real success to speak of thus far.
