Club Brugge picked up a shock 4-0 win at FCPorto win a second consecutive match in the Champions League and take the lead in Group B.
An early penalty converted by Ferran Jutgla was followed by two quick goals after half-time from Kamal Sowah and Andreas Skov Olsen before a late effort from teenage substitute Antonio Nusa sealed a huge upset.
The Belgian champions were worthy winners as they added an unexpected triumph to last week’s home success over Bayer Leverkusen.
Brugge are down to six points while Porto are bottom with no points.
The Belgians, who finished bottom of their group last season, took the lead after 15 minutes when João Mario brought down Jutgla and the new Spanish signing from Brugge found himself at the Estadio Dragão to convert the blow of foot.
Porto, who suffered a last-minute defeat at Atlético Madrid last week looked uneasy and failed to conjure up a response with his only real chance in the first half going to winger Pepe, whose effort was stifled by Simon Mignolet.
Two minutes into the second half, Jutgla attempted to dribble past a maze of defenders at the edge of Porto’s penalty area and, as the ball strayed away from him, it accidentally fell on Sowah to clear a path and score at close range.
Porto’s defense had been taken aback by the Ghanaian striker’s quick-wittedness and were again static as Brugge led 3-0 in the 52nd minute. Bjorn Meijer hit a low cross from the left which was allowed to go all the way to the other side where an unmarked Skov Olsen was able to fire home under Diogo Costa.
Raphael Onyedika’s 86th-minute effort returned on the right but Brugge got a fourth as Nusa, on their Champions League debut, pulled away from the defense to finish with a composure that belied their 17 years.
Atlético were on the receiving end of a late show at Leverkusen in Group B this time. The Spanish side scored twice in stoppage time to beat Porto last week but saw Robert Andrich and Moussa Diaby score in the last six minutes in Germany for a 2 -0 victory.
Edin Dzeko inspired International to a 2-0 win at Viktoria Pilsen. With Romelu Lukaku still sidelined with a thigh problem, Dzeko stepped up with a nice curling opener after 20 minutes and helped Denzel Dumfries wrap up the points in the 70th minute.
At the bottom of the table, Plzen had already been reduced to 10 men by this stage after Pavel Bucha received his marching orders on the hour mark.
Eintracht Frankfurt joined Spurs with three points in Group D after claiming a 1-0 victory in Marseilles. Jesper Lindstrøm provided the breakthrough two minutes before the break and despite the arrival of Mattéo Guendouzi and Cengiz Under, the hosts suffered a second successive defeat in the competition.
