A Romelu Lukaku goal in the first leg between Porto and Inter Milan was the decisive moment in the tie as both sides played out a stalemate in the second leg at the Estadio Do Dragao.
In a game that had few and far chances between, a defensive masterclass from Simone Inzaghi's side meant Porto were unable to find a telling breakthrough.
Notable chances in the game saw Edin Dzeko be denied by a strong Diogo Costa save in the first half, whilst the combination of a terrific Andre Onana fingertip save and the crossbar denied the Portuguese side an equaliser deep into stoppage time.
The Italian side will now await to see who they will face in the Quarter-Finals of the Champions League when the draw takes place on March 17th in Switzerland.

Diogo Costa - 7
Provided calmness on the ball and the occasional superb pass, whilst also denying Dzeko with a strong hand in the first half to keep the score level.

Ivan Marcano - 6

Denzel Dumfries - 6

Federico Dimarco - 6
Couldn't manage to get high up the pitch for the visitors but was defensively solid.
Nicolo Barella - 7
The best of the midfield three for Inter. Did well to keep possession and drove forward with the ball on multiple occasions before being replaced by Marcelo Brozovic late on.
Hakan Calhanoglu - 6
Typically impactful, the Turk didn't manage to leave his usual stamp on the game but still was able to create a few chances and kept possession well.

Danilo D'Ambrosio (70') - 6
Provided energy off the bench but didn't have much impact at either end of the pitch.

A completely different option to Dzeko, the man who got the tie clinching goal in the first leg used his body well and almost set up Martinez late on.
Stefan De Vrij (74') - 6
After replacing the injured Bastoni, the Dutchman filled in well and helped ensure Inter remained solid for the final 15 minutes of the game.

Milan Skriniar (80') - 6
Replacing the excellent Darmian on the night, Milan Skriniar along with Stefan De Vrij off the bench maintained a compact Inter backline to see out the victory.
