Arsenal have secured their place in the Champions League round of 16 thanks to a 2-0 over Borussia Dortmund at the Emirates on Wednesday evening.
The Gunners needed just a point at home to seal qualification and their victory over Die Schwarzgelben now gives them a chance to claim top spot, a feat which could see the Londoners avoid a potentially tricky last 16 draw.
And it was Sanogo, who featured in the starting XI due a Danny Welbeck injury, who got Arsenal off to the ideal start, who exchanged a clever backheel to Santi Cazorla, before slotting through the legs of Roman Weidenfeller off the Spaniard's through-ball within 73 seconds of the kick-off.
Despite an attempt from Dortmund to level the scores, Alexis Sanchez put the match to bed in the 57th minute when he curled a shot into the back of the net from the edge of the box to seal the victory.
"I liked what he (Sanogo) did tonight because we decided to go long to him and he protected the ball very well, what he did on the first goal was class, his link-up play with Cazorla, but unfortunately he got injured.
Following the match, Dortmund coach Jürgen Klopp conceded that Arsenal were 'deserved winners'.
"It was the worst possible start to concede such a quick goal," Klopp said at a press conference. "There were situations and moments when we did what we wanted but those periods were very short.
"Too many times we were not that great and Arsenal were the deserved winners tonight. We just weren’t good enough.
"We could have done better, we were not courageous tonight. There are 1000 reasons why we were not that good tonight. We have to work.
For Arsene Wenger though, the win comes at a cost as both Sanogo and Mikel Arteta came off injured, with the latter a concern from the manager.
"That doesn’t look good, it’s the calf," he told Sky Sports. "It’s very difficult to take on the chin because we are going into many games and you need everybody available, but I think Arteta will be out for a while."
There was better news over at St Jakob-Park as defending champions Real Madrid saw off Basel 1-0, claiming the club record of 15 consecutive wins in the process.
Ballon d'Or holder Cristiano Ronaldo scored the only goal of the game as he slotted home from close range in the 35th minute, matching Raul's tally of 71 Champions League goals in the process.
