Second stage
The Second stage was a two-legged knockout tie, with the draw regionalised.
Qualification and draw
The 32 qualifiers (17 group winners and 15 best performing group runners-up) were divided into two pots. Pot 1 contained the 16 best performing group winners. Pot 2 contained the worst performing group winner and the 15 qualifying group runners-up. In pot 1 the teams were numbered 1 to 16 in numerical order of the group they qualified from. In pot 2 the teams were numbered 17 to 32 in numerical order of the group they qualified from. In the case that one of the qualifying runners-up was from the same group as the worst performing group winner, both teams would be in pot 2 and the group winner would be numbered lower in sequence than the group runner-up.
To keep the draw regionalised Team 1 would play Team 18, Team 2 would play Team 17 and this pattern was repeated throughout the draw. The higher numbered team would play at home in the first leg.[3]
