Just four clubs remain as the battle to be crowned Europe’s number one intensifies.

The first of the Champions League semi-finals sees surprise packages RB Leipzig face Paris Saint-Germain on Tuesday evening and here is our look ahead to the encounter in Lisbon.

PSG finally realising their Champions League potential?

Given their European pedigree, it’s pretty surprising that PSG have failed to win the Champions League and perhaps it’s even more surprising that this is their first time in the semi-finals in 25 years. They didn’t make it easy for themselves in the quarterfinals either, with two last-gasp goals edging them past Atalanta. We all know the attacking prowess that Thomas Tuchel’s side have, but they finally seem to have found a way to stop shipping goals.

Tuchel’s team are 3/4 for a victory in 90 minutes here, while they are just 2/5 to qualify for the final. As has become customary, they’ll be relying on Neymar and fit-again Kylian Mbappe for the main source of their goals and the pair are 9/2 and 10/3 respectively to score first on Tuesday evening.

Considering PSG have scored in 33 successive matches in the Champions League, it’s not hard to see why they are just 4/7 to score first. William Hill are also offering enhanced odds of 4/1 on them scoring in both halves too.

Leipzig on the crest of a European wave

While PSG are expected to feature in the deeper stages of Europe, the same can’t be said of Leipzig who continue to defy expectation in this season’s Champions League. Many forget this is a side that was formed just 11 years ago, so to be where they are is quite incredible and they’ll be over the moon to have got this far.

At 33, Julian Nagelsmann is the youngest coach in history to reach a Champions League semi-final and he should take great credit for his team’s progress, particularly as it’s his debut season in the job.

In similar fashion to their opponents, the Germans left it late to book their place in the last-four, with Tyler Adams scoring the winner in the 88th minute against Atletico Madrid. Leipzig are 10/3 to win the match in 90 minutes, while they are 7/4 to qualify for the final.
