4) Nereo Rocco

Rocco was incredibly successful as manager of AC Milan, as well as being a pioneer of the ‘catenaccio’ style of play. During his time at the club they dominated the domestic scene in Italy, winning two Serie A titles and three domestic cups. All this is however, trumped by the club’s performance in Europe during his three spells in charge of the team. The European Cup was won twice, in 1963 and 1969 respectively, with Rocco also leading AC Milan to European Cup Winners’ Cup success on two occasions. He was inducted into the Italian Football Hall of Fame in 2012.

3) Sir Alex Ferguson

Ferguson was a giant of the British game during his legendary tenure at Manchester United. So much so, that it is often forgotten just how successful he was during his time in charge of Aberdeen. Domestically the manager managed to break the Old Firm’s dominance by winning the Scottish championship. His greatest triumph in charge of the Scottish side must be seen as his 1983 European Cup Winners’ Cup campaign, with Aberdeen defeating the mighty Real Madrid 2-1 in the final. The Scotsman would add the 1991 European Cup Winners’ Cup to his collection during his, less successful, early years at Manchester United. Whilst Ferguson’s dominance of the British game for all of the Premier League era goes unquestioned, his critics have often argued he should have won more than the two Champions League titles he did, in 1999 and 2008 respectively. Although, the 1999 triumph is considered one of the tournament’s greatest, with United only equalising and then taking the lead in second half stoppage time.
