Napoli or Manchester City, Manchester United or Basel, Ajax or Lyon - the teams that can qualify for the Champions League last 16 on matchday six

We have finally arrived at the business end of the 2011-12 Champions League group phase. After matchday five, nine teams safely booked their ticket to the last 16, and after Tuesday's matchday six fixtures, three more spots have been procured, leaving just four more up for grabs.

AC Milan, APOEL, Arsenal, Barcelona, Bayern Munich, Bayer Leverkusen, Benfica, Chelsea, Inter, Marseille, Real Madrid and Zenit St. Petersburg can now all breathe a sigh of relief knowing that they will be back in action in Europe's premier club competition in February when the knockout stage kicks off.

But for Ajax, Basel, Lille, Lyon, Manchester City, Manchester United, Napoli and Trabzonspor, these eight teams will have to make one final push on Wednesday to secure the remaining four berths to the last 16.

Whose Christmas will come early?
