Mircea Lucescu, 80, had stepped down from his role as Romania boss just five days earlier after he collapsed in a team meeting.
He then suffered a heart attack the next day and was taken to the University Hospital in Bucharest, where he failed to recover.
The manager’s death led to mourning in Romania and tributes being paid.
He will now be honoured with Dinamo Bucharest’s new stadium being named after him.
Lucescu managed the club between 1985 and 1990, winning a Romanian league title and two domestic cups.
The honour was confirmed by Romania’s Minister of Internal Affairs Catalin Predoiu after the funeral.
He said: “We decided to initiate legal procedures to name the future stadium Dinamo – Mircea Lucescu.”
The new stadium is currently being built on the side of the old Dinamo Sports Park.
There will be a huge increase in capacity for fans with 11,000 seats being added compared to the 15,000-capacity venue.
The old ground was opened in 1951 after Dinamo was founded and included an athletics track and oval stands.
The construction of the new ground is estimated to cost nearly £82million and is expected to be finished by 2029.
Lucescu was still in charge of Romania when they lost their World Cup play-off semi-final against Turkey on March 26.
That effectively brought an end to his second stint as boss of his homeland – the first of which came in the 1980s.
He also managed the likes of Inter Milan, Shakhtar Donetsk and Turkey during a 47-year managerial career which took him all around Europe.
The Bucharest-born coach became only the fifth person to manage 100 Champions League matches when he surpassed the mark in 2015.
That put him in esteemed company with only Sir Alex Ferguson, Carlo Ancelotti, Arsene Wenger and Jose Mourinho getting there sooner.
Lucescu is the third most successful manager ever in terms of trophies won.
