A 0-0 draw against Aris Salonika on Tuesday would appear to give City the advantage going into the second leg at Eastlands next week.
However Wright-Phillips is cautious about their prospects, knowing the Greek side completed the double over current holders Atletico Madrid earlier in the campaign.
He said: "We know how dangerous they can be just from playing them and from video clips. We know how well they defend and how well they break.
"We will need to have our wits about us and that is why we know it won't be a formality. We could have snatched a victory but we will take the draw at the minute."
