The Chinese Super League giants, regarded by many as favourites for the tournament, drew first blood in their last-eight meeting with Lekhwiya on Wednesday after cruising to victory at the Tianhe Stadium, thanks to second-half goals from Dario Conca and Elkeson.
But given his side failed to make the most of their chances and claim a healthier lead, Lippi believes they have to be wary heading into the return encounter on September 18 as the tie is still far from over.
"It was a good match from our point of view, even though we had a lot of chances and couldn't take more of them," he said on the AFC's official website.
"I am happy but there is 180 minutes in this match so our goal is to go to Qatar and win. We got the penalty [for Conca's opener] but we had many chances before that we could not take.
"There is still a month until the second game so we will wait until then to think about what we will do."
The legendary 65-year-old, who led Italy to victory at the 2006 FIFA World Cup, also reserved special praise for Elkeson, who was making his Champions League debut on Wednesday.
"Elkeson came in with an aggressive attitude against their [Lekhwiya's] strong defenders," Lippi added.
"He scored a beautiful goal and also had many opportunities with headers.
"We can't finish every match in the first few minutes. We have reached the quarter-finals of the AFC Champions League, which is a very important tournament for us.
"We did create many chances and we won 2-0, which is very satisfying."
Evergrande look destined to be crowned Super League champions again this season as they currently hold a 14-point lead at the top of the table.
