#4 Subrata Bhattacharya's derby debut against Mohun Bagan
Have you ever imagined Francesco Totti taking the managerial role at Lazio, or Paolo Maldini on the touchline shouting out instructions at the players of Internazionale? This particular scenario was almost as disturbing for the Mohun Bagan fans, as the ones mentioned above and it became a reality in 2007 when Bagan legend Subrata Bhattacharya took over the reigns at East Bengal.
The largely unpopular spell came to an end shortly after the derby when Bhattacharya's side failed to beat his former club when the two iconic teams from Bengal played out a thrilling 4-3 encounter.
The game is still considered to be one of the greatest ever in the history of the Derby and the controversy surrounding Bhattacharya's role in the fixture is still unforgivable in the eyes of the Bagan faithful.
