After some really interesting first-leg matches, the next two days will be a delight for soccer fans with four interesting matches, three of which should not be missed.

Chelsea go to Spain and will really need to steal a goal in Valencia. I expect Valencia to play quite defensive knowing quite well that, like Inter Milan in the last round, Chelsea can score goals with almost anyone on their squad. With that, while Valencia do have the home field advantage, I still think Chelsea can manage a goal, but the question will be can Valencia score two to seal the deal. My money is on Chelsea for the time being, but this one could still go either way.

Prediction: Valencia v Chelsea 0:1

United are in trouble, after beling claimed by professional analysts as the best team in Europe, they have lost two straight, their lead in England is only three points and they need to score a goal to advance to the Semis. For them thankfully, they do have that one away goal to help them out, but I think that Roma will be able to score in Manchester and I fear that there won't be enough time on the clock for Man Utd to get back into this game. But if Man Utd can score early, Roma will probably change their tactics and that could lead to counter-attack oppertunities for Man Utd and two or more goals can be scored. I doubt SAF and his side will suffer another loss, so I'm thinking a Man Utd win, but it won't be easy

Prediction: Manchester United v AS Roma 1:0

Liverpool will be heading to the final four, it's just a question how they go in. With their 3:0 away win last week, they booked a shot to head to Athens but now must decide if they want to relax and play a defensive match or continue their offensive attacks and continue to build momentum into the semis. I don't expect any of the key players (Gerrard, Reina, Crouch) to start to save them for injuries and card suspensions. Even with that, I still see them being a stronger side and another victory in the cards

Prediction: Liverpool v PSV Eindhoven 2:0

Out of all the matches, the Bayern v Milan match should be the best one. Milan in my eyes, were not anything special last week and were lucky to get the Penalty call and foolish to let up near the end to give Bayern the edge going into this match in Munich. I think Bayern will manage at least a goal and that puts pressure on Milan to score twice. Even if Milan score first, Bayern can rebound and level the scoreline with their threats upfront. This match could end in a tie, but it won't be a shoot-out tie, but a low-goal one.

Prediction: Bayern Munich v AC Milan 1:1
