Round 4 will be played this weekend from Portugal's Primeira and we will enjoy some very interesting clashes.
On Saturday CD Aves will host FC Famalicão in search for an important win.
Last season the away side played in Portugal's second league, which is very surprising considering their unbeaten start of the new season.
Sporting CP will face an easy obstacle on Saturday when they will play at home Rio Ave.
The home side are the temporary league leaders, so they will try to resume on the top after this week's round.
One rather interesting clash from this weekend will be the match between Sporting Braga and SL Benfica.
Last time, SL Benfica were heavily beaten at home by FC Porto, which put some concerns about their upcoming performance.
FC Porto will aim for another important win when they face at home the team of Vitória Guimarães.
The away side's performance hasn't been bad as the team haven't conceded any losses from the start of the new season.
