Domenico Tedesco's Bundesliga side made it 10 games unbeaten across all competitions with a 4-1 thumping of Borussia Dortmund on Sunday but found itself behind at the Red Bull Arena when Luis Muriel struck after 17 minutes.

Gian Piero Gasperini's visitors thought they had escaped lightly when Andre Silva saw his penalty saved by Juan Musso after the break, but Davide Zappacosta miscued into his own goal to restore parity.

Neither team could find a late winner, with Teun Koopmeiners and Dominik Szoboszlai denied by the woodwork, which leaves it all to play for in the return leg next Friday.

Christopher Nkunku skewed a half-chance wide from Benjamin Henrichs' mishit strike in an otherwise uneventful opening to the contest.

But Muriel sparked the tie into life when he ghosted inside from the left flank before expertly whipping into the top-right corner for his fourth goal in European competition this season, his best tally.

Muriel almost repeated the trick shortly after but his left-footed drive narrowly evaded the far corner, before the woodwork denied Silva and Mario Pasalic at either end.

Peter Gulacsi pushed away a teasing Muriel curler from range after the interval, before Merih Demiral needlessly felled Nkunku inside the area.

Musso denied Silva's spot-kick before an excellent reflex save thwarted Willi Orban on the rebound, but Leipzig equalised moments later when Zappacosta inadvertently turned Angelino's cross into his own net.

Gulacsi then tipped a low Koopmeiners effort onto the post and Szoboszlai headed onto the crossbar, while Lukas Klostermann saw a late strike denied on the line following a goalmouth scramble from Emil Forsberg's corner as neither side could be separated.
