Former Manchester United favourite Ronaldo has been at Madrid since 2009 The draw for the last 16 of the 2012/2013 UEFA Champions League has paired Manchester United with Spanish giants Real Madrid. The tie will see Cristiano Ronaldo return to Old Trafford for the first time since his £80m move from United to Real in June 2009. Elsewhere, Celtic have been drawn against Italian side Juventus, Arsenal take on last year\'s beaten finalists Bayern Munich and Barcelona will play AC Milan.
Borussia Dortmund face Shakhtar Donetsk, Valencia play Paris Saint-Germain, Porto take on Malaga and Galatasaray will tackle Schalke.
The draw of the 16 group winners and runners up from the first round of the Champions League took place on Thursday at the UEFA headquarters in Nyon, Switzerland. Amazingly, all eight ties drawn in the actual draw were the same as those seen in the final rehersal
The match between Bayern and Arsenal pits Bayern\'s German national team stalwarts such as Bastian Schweinsteiger, Philipp Lahm, Manuel Neuer, and Thomas Müller against their national team teammates from Arsenal, Lukas Podolski and Per Mertesacker. Podolski also used to play for Bayern.
\"We know Arsenal well. That\'s a draw we can be satisfied with,\" said Bayern\'s chief executive, Karl-Heinz Rummenigge. \"That game won\'t win itself, we can\'t underestimate Arsenal.\"
Dortmund\'s chief executive Hans-Joachim Watzke was a bit more pessimistic in his comments to Sky TV.
\"That\'s not necessarily the opponent we\'d chose,\" he said, referring to Ukrainian side Shaktar Donetsk. \"That\'s a difficult task, but we showed in the group phase that we can pull through against strong opponents.\"
Schalke\'s captain, Benedikt Höwedes, said his team was got a \"decent draw, but we certainly won\'t underestimate Galatasaray.\"
Last year\'s Champions League winners, Chelsea, failed to advance to the Round of 16 after finishing third in their group. As a result, they move into the Round of 32 in the Europa League.
