After a dramatic end to the Champions League groups, the four
English teams now know the sides they could face in the knockout stages.
Ahead of Monday's draw in Nyon, Sportsmail has broken down the clubs they could meet in the last 16 of the competition.

Top dog: Cristiano Ronaldo will be keen to add to his record amount of group stage goals for Real Madrid in the knock-out stages
After slumping to second in their group after a final loss against
Napoli, Arsenal now face what appears to be a much tougher draw in the
knockout stage.
The basics of the draw state that no side can meet a team from their own group or their own association, with the top seeded team (the group winners) playing the second-leg of their last 16 tie at home.
That means none of the Premier League sides can play each other, but it leaves the Gunners and Manchester City open to be drawn against the big hitters in the competition after finishing as runners-up.

Fighting fit: Lionel Messi will return from injury to lead Barcelona's assault on the Champions League
Both are looking at the prospect of meeting Spanish giants Real
Madrid and Barcelona, while Arsene Wenger's team could also be drawn
against the reigning champions in Bayern Munich - City cannot face
Bayern but could be drawn against last year's finalists in Borussia
Dortmund.
For Chelsea and Manchester United - their toughest draw on paper appears to be a meeting with AC Milan. Even so, the two group winners will be favourites against any team they draw in the knockout stages.
