The second round of Primeira Liga matches produced several surprise results, with Sporting and FC Porto drawing 1-1 against Paços de Ferreira and Marítimo respectively on Saturday.

Benfica failed to take advantage on Sunday night as the Eagles fell to a 1-0 defeat at Arouca. The result puts Lito Vidigal’s team on top of the league. After just two rounds of matches, Arouca are the only team with a 100% winning record. 

PortuGOAL rounds up the weekend action.

Brazilian left-back Alex Sandro has traded the blue and white of Futebol Clube de Porto for the white and black of Massimiliano Allegri’s Juventus after four years in the north of Portugal.

Porto receive €26 million for the transfer, which brings their summer income from transfers to over €100 million – a club record for one transfer window.

More worryingly for Porto fans, it brings the number of departures of key players from last season’s side to six: Jackson Martínez, Danilo, Óliver Torres, Casemiro, Ricardo Quaresma, and now Sandro.

Slimani hits late winner

In-form CSKA have a vital away goal but Sporting are ahead on aggregate after a fast-paced and highly entertaining game at the Alvalade to make Jorge Jesus's record 3 wins from 3 matches as Sporting manager.

Colombian Teófilo Gutiérrez put Sporting ahead early on before Rui Patrício saved a penalty. Seydou Doumbia equalised for CSKA but Islam Slimani grabbed the winner as Sporting left it late again ahead of tough second leg.

The season has only just begun, but Sporting face one of their most important matches of 2015/16 tomorrow evening as the Lisbon club welcome CSKA Moscow to the Portuguese capital in the first leg of the Champions League play-off.

The Lions have unhappy memories of the last time the Russian outfit visited the Alvalade. Home advantage counted for nothing as the Muscovites beat Sporting 3-1 in the 2005 Uefa Cup final to deny Sporting European glory.

Can Jorge Jesus’s men exact a measure of revenge for that painful night a decade ago? It won’t be easy. Russian football expert and UEFA.com commentator John Bradley gives PortuGOAL the lowdown on CSKA.
