Santa Clara are officially back in the I League, as a result of the draw by AVS in their trip to the Estádio do Mar, against Leixões, which left Jorge Costa's men mathematically unable to 'assault' the leadership, due to the disadvantage in the direct confrontation. Nacional achieved the same feat, thanks to the triumph over Tondela, by 2-3, in a match in which they were at a disadvantage after only 34 minutes, as a result of a penalty converted by João Costinha, following a foul committed by Ulisses on Daniel dos Anjos in a 'no-go zone'. Tiago Margarido's men returned from the locker rooms 'fired up', and turned the game around, with two goals, by Jesús Ramírez and Carlos Daniel, in eight minutes. A penalty by Daniel dos Anjos restored equality, but already in stoppage time, Carlos Daniel sealed the final result. Having done the math, one round before the end, the leadership passes, provisionally, into the hands of Nacional, with 68 points, one more than Santa Clara, who will still visit Mafra, and four more than AVS, who can now only aspire to the promotion playoff. Marítimo is fourth classified, with 60 points, which means that a triumph in the reception to Oliveirense, still this afternoon, will leave them a minimum distance from Jorge Costa's men, at the start of the final round. Leixões, on the other hand, with this result, mathematically guarantees their permanence, since, with only one game left to play, they are 15th classified, with a four-point advantage over Feirense, the team that lives immediately below the 'waterline'.
