Bayern Munich host Paris Saint-Germain in Germany tonight for a Champions League semi-final second leg that promises to be nothing short of spectacular. The winner will face Arsenal in the final, but before that, we could witness history in the making.

The first leg in Paris was a goal-fest, with nine goals scored between two attack-minded sides. PSG hold a slender one-goal advantage heading into the return match, but if defending was scarce in the first game, fans will be hoping for more of the same open, free-flowing football tonight.

So, where does this tie rank among the greatest Champions League semi-finals? And how many more goals are needed to break the all-time record?

Already, after just one leg, this semi-final has produced more goals than all but four other two-legged ties in the Champions League era (since 1992). The list of high-scoring classics includes Juventus 6-4 Monaco (10 goals), Manchester City 5-6 Real Madrid (11 goals), and two ties currently tied for the record: Liverpool 7-6 AS Roma and last season's Barcelona 6-7 Internazionale, both with 13 goals.

That means if tonight's match ends with a result like 3-2 to either side, the aggregate tally would hit 14 goals—a new Champions League record. For context, a 2-2 draw would also break the mark, while a 1-1 stalemate would keep things level.

But what about the old European Cup? One semi-final stands above all others. Way back in the 1959/60 season, Eintracht Frankfurt dismantled Rangers 6-1 in the first leg before finishing the job with a 6-3 win at Ibrox, for a staggering 12-4 aggregate victory. That 16-goal thriller remains the all-time record for any European Cup or Champions League semi-final.

Tonight, we're just seven goals away from matching that historic mark. Given the attacking firepower on display and the openness of the first leg, don't be surprised if we see that record challenged—or even broken. For fans of thrilling, end-to-end football, this is a must-watch.
