ManUtd.com is assessing the Reds' five potential Champions League last 16 opponents, including Italian giants AC Milan…
How did they fare in Group H? The Rossoneri finished four points behind leaders Barcelona and had to survive a nervous final game against Ajax. Defeat to the Dutchmen would have resulted in elimination and Riccardo Montolivo's red card for a foul on Christian Poulsen after only 22 minutes hampered the hosts' cause. Milan may have only beaten bottom side Celtic in the pool but did earn a creditable home draw with Barca in October.
What was their standout result? Parkhead can be a very intimidating place to visit and Neil Lennon's Celtic are often difficult to beat at home. Indeed, the Bhoys were only sunk by a solitary strike by Barcelona's Cesc Fabregas and saw off Ajax 2-1 in their other fixtures in Glasgow. When the Italians came to town, Kaka, Cristian Zapata and Mario Balotelli scored the goals in a resounding away victory that silenced the noisy home faithful.
Who are the men to watch? United know all about Balotelli and nobody will forget his displaying of the 'Why always me?' t-shirt after scoring at Old Trafford in the derby for Manchester City. The unpredictable striker can be world class on his day while Nigel de Jong and Robinho also have links with the Blues. Kaka, now 31, orchestrated the Reds' downfall in the 2007 semi-finals and clearly still retains his quality on the ball but the biggest threat may come from Italy international forward Stephan El Shaarawy. The spiky-haired youngster has proved his worth since arriving from Genoa.
