Porto vs Arsenal last five H2Hs
Arsenal 5-0 Porto – 9th March 2010
Arsenal's last encounter with Porto was a memorable one with the Gunners running riot at the Emirates Stadium in the Champions League Round of 16.

Porto 2-1 Arsenal – 17th February 2010
The only previous occasion that Arsenal and Porto have been drawn to face each other in the Champions League Round of 16 came in 2010. Like this year, the first leg was played in Porto and the Portuguese outfit had a night to remember as they ran out 2-1 winners. Valera gave the home side the lead early on before Sol Campbell equalised for the Gunners before half time. Falcao ensured Porto would head into the second leg with the lead when he scored in the 51st minute.
Porto 2-0 Arsenal – 10th December 2008

Porto 0-0 Arsenal – 6th December 2006
The only time Arsenal have avoided defeat at the Estadio do Dragao came in December 2006 in their final Group G fixture. Arsenal knew that a point would be enough to see them qualify for the Round of 16 winners and they did exactly that in a game that was instantly forgettable. Arsenal's Champions League campaign didn't last much longer with PSV knocking them out in the Round of 16.

Potential MVP – Bukayo Saka
Bukayo Saka seems to save his best form for the Champions League and the England winger has returned to top form in recent weeks ahead of the competition's return. Saka scored three goals in five appearances in the Champions League group stages and he has scored six goals in his last four appearances in the Premier League which makes him Arsenal's most dangerous and in-form player for this fixture.
