Kingsley Coman netted another vital Champions League goal against his former club Paris Saint-Germain as Bayern Munich claimed a 1-0 lead from the away leg of their last-16 tie.

Paris-born Coman scored the only goal when Bayern beat PSG in the final three years ago, and he repeated the trick at the Parc des Princes on Tuesday.

The first-leg victory was no more than Bayern deserved, and the Bundesliga giants will hope they do not pay the price for winning by just one goal against a PSG side who played without Kylian Mbappe until the 57th minute.

Mbappe, returning from injury, was introduced soon after Coman's goal and could not inspire a turnaround – seeing a late equalizer disallowed – but his involvement in the return match in Germany could yet be decisive.

Without Mbappe from the outset, PSG were completely outclassed, albeit Coman's strike early in the second half was their first clear-cut opportunity.

The winger's finish from substitute Alphonso Davies' cross was close to Gianluigi Donnarumma, but it crept beneath the goalkeeper, who still has not kept a clean sheet in the Champions League this season.

Mbappe's introduction did little to slow Bayern, and Donnarumma was far more impressive in keeping PSG in the tie, making instinctive stops from Eric Choupo-Moting and Benjamin Pavard.

Finally, with 17 minutes to play, Mbappe got in at the other end, but Yann Sommer blocked bravely, and the PSG forward was still in an offside position when Neymar's subsequent shot was spilled at his feet.

That was a straightforward call for the linesman, but the VAR was required when Nuno Mendes dashed in behind and squared for Mbappe to score. The celebrations were cut short as replays showed the left-back had strayed offside.

Although Pavard was sent off for a second bookable offense in stoppage time, Bayern have control heading back to Bavaria.
