RB Leipzig picked up a point on their Bundesliga debut with a last-gasp goal earning them a 2-2 draw at Hoffenheim.Lukas Rupp, a summer signing from Stuttgart, put the hosts in front with a sweetly-struck volley after Leipzig failed to clear a corner beyond the edge of their own penalty area.Leipzig, who had enjoyed the better of the first half and brought numerous good saves out of goalkeeper Oliver Baumann, were not behind for long, though.Dominik Kaiser brought Leipzig level with their first ever Bundesliga goal - a fine front-post finish from Diego Demme's cross, guiding the ball into the far corner of Baumann's goal.A wayward Leipzig pass was punished in the 83rd minute when it was picked up by Sebastian Rudy, who played the ball into the path of Mark Uth and he put Hoffenheim back in front.But Marcel Sabitzer levelled in the last minute, meeting Benno Schmitz's cross at the far post to earn Leipzig a point.ends
