The striker assisted the opener before doubling his side's lead as they put four past their Russian visitors
Moussa Marega was on song as Porto handed Lokomotiv Moscow a 4-1 defeat in Tuesday's Uefa Champions League outing.
The Mali international continued from where he stopped in the last matchday against the same opposition after he laid on an early opener for Hector Herrera to put the hosts in front two minutes after kick off.
In the 42nd minute, Marega doubled his side's lead off an assist from the Mexico midfielder.
Jefferson Farfan pulled one back for the Russians but Jesus Corona's strike and a late Otavio effort wrapped up a comfortable victory for the Portuguese champions.
