After the Colombia U-23 men's side secured their ticket to Rio de Janeiro by defeating their USA counterparts in their inter-continental play-off last month, all 28 slots at the Olympic Football Tournaments Rio 2016 have now been filled. The nations involved are surely waiting with baited breath for the draw, to be held at the Maracana on 14 April 2016 and FIFA.com is here to guide you through the nuts and bolts of the draw process.

Hosts Brazil will take the lead spot in Group A (men's) and Group E (women's), with the men's teams allocated into four pots based on a ranking built according to performances at the past five Olympic Football Tournaments. The ranking is weighted so that recent performances play a more prominent role, and a bonus is given to those nations who finished their qualifying competition as continental champions.

Brazilian superstar Ronaldinho, who won an Olympic bronze medal at Beijing 2008 and former Brazil captain Aline, who picked up a silver medal at Athens 2004, will help with proceedings as draw assistants.

The 16 sides will be drawn into four groups of four (named Groups A-D), and the pot allocation for the Men's Olympic Football Tournament is as follows:

Pot 1: Brazil, Argentina, Mexico, Japan
Pot 2: Nigeria, Korea Republic, Honduras, Iraq
Pot 3: Sweden, Fiji, Portugal, South Africa
Pot 4: Algeria, Colombia, Denmark, Germany

The women's sides will also be split into four pots, but their allocation to the pots will be based on the FIFA/Coca-Cola Women's World Ranking released on 25 March.

The 12 sides will be drawn into three groups of four (named Groups E-G), and the pot allocation for the Women's Olympic Football Tournament is as follows:

Pot 1: Brazil, USA, Germany
Pot 2: France, Australia, Sweden
Pot 3: Canada, China PR, New Zealand 
Pot 4: Colombia, South Africa, Zimbabwe 

The general principle for each tournament's draw is to ensure that no group has more than one team from the same confederation.

The draw is scheduled to kick off at 10.00 local time (15.00 CET), and for a more detailed breakdown of the draw mechanics, constraints and seeding you can read the Official Draw Procedures.
