To stay in the game and qualify for the next round of 16, Uruguay have to defeat Italy at Natal's Das Dunas Stadium while Italy only needs a draw to advance.
Lugano, who will likely sit out the game due to a knee injury, added, "we want to win the easy games but turn them into difficult ones and sometimes the difficult ones become a little easier."
Uruguay lost 1-3 to Costa Rica in their first match but bounced back to beat England 2-1, with two goals from star striker Luis Suarez.
"With just a few hours to go before this momentous match, this enormous and incredibly difficult challenge, I only ask that all Uruguayans be united in cheering for the (national team)," wrote Lugano.
