I see Madrid knocking out City (City have been atrocious of late). PSG vs Dortmund could be a very interesting tie, but I still give the edge to PSG - they have more weapons and the 2nd leg at home. ATM vs Liverpool could be closer than many anticipate, but there's only one winner here. Napoli vs Barcelona could provide a surprise - Barca have been largely unconvincing, and Napoli seem to be buying into Gattuso's philosophy.
We should dispatch Lyon, but we might actually make it more difficult for ourselves than it should be. Bayern should defeat Chelsea with relative ease, not because Bayern are great, but Chelsea are just too incompetent (novice coach, inconsistency, too many holes in their game). Atalanta vs Valencia is really anyone's tie - Atalanta score for fun, but they also seem to concede with regularity, and throw away games they should be winning - I'd give Valencia the edge due to their European experience/pedigree. Spurs vs Leipzig is another intriguing tie that could go either way, but I give the slight edge to Spurs.
Predictions:
ATM vs Liverpool (2-4 on aggregate. Liverpool draw 1-1 in Spain and complete the job 3-1 at home)
Lyon vs Juventus (2-3 on aggregate. We get a 1-1 away from home and scrape through after a 2-1 home victory)
Dortmund vs PSG (4-5 on aggregate. 2-2 in Germany and PSG winning 3-2 @ home)
Madrid vs City (4-3 on aggregate. 1-1 in Manchester and a 3-2 Madrid win in Spain)
Napoli vs Barcelona (4-4 on aggregate. 2-2 in Naples and 2-2 in Spain. Barcelona win on penalties.)
Atalanta vs Valencia (3-4 on aggregate. 2-1 in Italy with Valencia winning 3-1 in Spain)
Chelsea vs Bayern (2-4 on aggregate. Bayern win both legs 2-1)
Spurs vs Leipzig (3-3 on aggregate. 1-1 in London with Spurs qualifying on away goals after a 2-2 draw in Germany)
Liverpool, Juventus, PSG, Madrid, Barca, Valencia, Bayern, and Spurs in the QFs. I'd love Valencia or Spurs in the QFs please.
