Razgrad, Bulgaria (SportsNetwork.com) - Liverpool disappointing form continued as the club conceded a late goal at Ludogorets Arena to settle for a 2-2 draw with Ludogorets in Group B of the Champions League on Wednesday.

The Reds entered the contest on a run of four straight defeats in all competitions, and things appeared to worsen inside the opening three minutes of Wednesday's clash as Dani Abalo pounced on a gaffe from Simon Mignolet to open the scoring for the Bulgarian side.

Liverpool managed to draw level in the eighth minute when Rickie Lambert capitalized on some defensive miscommunication to nod home his second goal in as many starts.

The Reds then took the lead in the 37th when Jordan Henderson made a late run to the back post to connect to Raheem Sterling's superb pass across goal and steer the delivery home from close range.

It looked as if Liverpool had done enough to clinch all three points, but Ludogorets stole an equalizer two minutes from time when Georgi Terziev nodded a corner kick past Mignolet at the back post.

In Wednesday's other Group B clash, Cristiano Ronaldo produced the lone goal in Real Madrid's 1-0 defeat of FC Basel.

The results leave Liverpool with a strong chance of advancing to the knockout round, but the Reds must defeat Basel in their penultimate match of the group stage.

Real Madrid sits atop the group on 15 points, followed by Basel on six points and Liverpool and Ludogorets on four points apiece.

Arsenal bounced back from a disappointing league loss to Manchester United by claiming a 2-0 victory over Borussia Dortmund in a commanding performance in Group D action at the Emirates on Wednesday.

Yaya Sanogo made the most of a rare start by opening the scoring in just the second minute of play while Alexis Sanchez continued his fine season by curling home a splendid effort in the 57th minute.

The result sees Arsenal clinch a spot in the knockout round by bringing the Gunners to 10 points, two points adrift of first-place Dortmund. Anderlecht, meanwhile, collected a 2-0 victory over Galatasaray on Wednesday thanks to a brace from Chancel Mbemba Mangulu.

Atletico Madrid cruised to a 4-0 rout of Olympiakos at the Vicente Calderon on Wednesday to remain atop Group A. Raul Garcia opened the scoring for the hosts after only nine minutes while Mario Mandzukic completed the comfortable win by notching a hat trick the rest of the way.

Juventus moved three points clear of Olympiakos thanks to a 2-0 victory over Malmo on Wednesday. Fernando Llorente and Carlos Tevez netted the goals in the win, bringing the Old Lady to nine points through five games. The Italian side needs just a point from its clash with Atletico Madrid to clinch a spot in the knockout round.
