Who could Arsenal face in the Champions League quarter-finals? Mikel Arteta could draw showdown with Man City

Arsenal have overcome their Champions League last-16 curse, with a blockbuster tie potentially awaiting in the quarter-finals.
The Gunners went into their second leg clash against Porto 1-0 down, but managed to draw level in the tie through Leandro Trossard's goal.
That proved to be the only goal of the game as the round-of-16 clash went to a nerve-jangling penalty shootout, which Arsenal won 4-2 as David Raya saved twice.
With just under three weeks before their next fixture, Arsenal's attention will now turn to the draw for the competition's quarter-finals.
The semi-final draw will also be made, with the 'home' team decided for Wembley meaning Arsenal can start to map their road to glory.
There are no seeds in the quarter-finals or country protection, which means the Gunners could end up drawing Manchester City.
Defending European champions City have already comfortably sealed their place in the last eight having downed Copenhagen.
The two Premier League title rivals have never met in Europe, but Pep Guardiola has suffered a poor record against other English sides.
Since arriving at the Etihad Stadium, the Spaniard has seen City knocked out of the Champions League by Liverpool and Tottenham, while also losing the 2021 final to Chelsea.
Former last-16 foes Bayern Munich and Barcelona are both options as well, with Harry Kane and co already into the quarter-finals.
The 14-time winners Real Madrid are in the hat alongside Paris Saint-Germain, with Borussia Dortmund and Atletico Madrid available as well.
Arsenal will learn their quarter-final opponents on Friday, when the draw is completed.
Proceedings at the House of European Football in Nyon, Switzerland, will start at 11am UK time.
