Suarez feels Messi's strike – his first in nine matches against the Premier League outfit – will give Barca a boost heading into the second leg on March 14.
"It was a beneficial goal for the second leg to have more space at the Camp Nou," he said, via Marca.
"Our strength is being better at home, that's why it was important to score.
"Now they have to try to score at the Camp Nou and we'll have more space."
Barca struggled to create many chances before an Andreas Christensen error allowed Messi to equalise.
Despite his side's challenges, Suarez played down any suggestions he felt isolated during the first leg.
"I didn't feel alone up front," he said.
"In these games you have to be intelligent and look for the best solution.
"Seeing that Leo couldn't create chances, he dropped a bit deeper to find spaces."
