Here are Colin's Keys for a massive match against Miami.
Tighter defending
Miami have a very difficult attack to stop.
The 'Caps will need to be tighter in and around our box.
And we need to react quicker to the second phase.
The Miami effect
There's expected to be more than 50,000 fans at BC Place on Saturday.
The energy will be very high.
We need to make the occasion work in our favour with the crowd.
Quick counter
At times this season Miami have been exposed defensively.
The 'Caps will likely need to score more than once to win this match.
They can cause Miami problems with quick counter attacks and forward play.
