United vs Barca will be very interesting. Other than us, I think United have the speediest counter-attack left in the competition to take advantage of Barca's vulnerabilities – if they play their cards right, they genuinely have a chance and being the underdog in everybody's eyes will suit them.
Juve vs Ajax – hmm, the Ajax we saw at the Bernabeu could genuinely beat anyone, but not even their coach or players know if they can reach same level again. Juve are favorites, of course.
Spurs vs City – great draw for us, this will be exhausting tactical trench warfare in both games. Pochettino and Guardiola know each other's thinking and will spend countless hours trying to ruin each other's plans. I wouldn't rule out overtime and penalties.
LFC vs Porto – probably won't be so easy this time, but I can't see us not going through.
