Here are Colin's Keys to push past Portland at Providence Park.
Timbers in transition
The Timbers are one of the best teams in transition in MLS.
They can get up the field quickly.
We need to be very well organized when we have the ball.
Stay compact
From front to back, we need to be more compact and tighter defensively.
The onus is on the Timbers at home.
We'll take a scrappy win.
Pressure
Portland has scored 33 goals so far this season.
We must put pressure on them.
Do not let them get shots off.
