Liverpool were unable to beat Bayern Munich in their Champions League last-16 first leg tie at Anfield on Tuesday night.Jurgen Klopp’s side managed to keep a clean sheet despite being forced to deploy Fabinho and Joel Matip as their centre-back pairing in the absence of Virgil van Dijk and Dejan Lovren.However, they also failed to score against a Bayern side who haven’t managed to keep a clean sheet since December.A 0-0 draw isn’t a terrible result by any means - not conceding an away goal is, of course, a huge positive - but Klopp will have gone into the game hoping for a victory.His team are capable of scoring against any team in the world, especially at Anfield, and he’ll probably feel this was a missed opportunity.“I’m not over the moon but I’m completely okay with the game,” he told BT Sport after the match.Klopp wears his heart on his sleeve and often reacts badly to defeats or other disappointing results.Moments after the full-time whistle was blown against Bayern, the charismatic German coach was involved in what appeared to be a heated discussion with his opposite number, Niko Kovac.It’s unclear what Klopp was annoyed about but Graeme Souness - speaking on Virgin Media Sport in Ireland - had his say on the altercation.“It won’t be,” Souness repeated after the host questioned whether the chat was good-natured.“We don’t know if something’s just been said to him there. There was nothing obvious during the 90 minutes to warrant him being upset.“[He was] maybe frustrated at his team - a team that can get anybody at Anfield. I can only think of Man City off the top of my head in recent years that this team have not got to - put them under pressure, make the goalkeeper make saves - they didn’t do that tonight.“You’ve got to give credit to Bayern. They defended in numbers, were totally organised, I thought James [Rodriguez] and [Thiago] Alcantara would struggle tonight - they put a shift in with [Javi] Martinez in midfield.“You have to say Liverpool’s midfield huffed and puffed. I wanted to see more from their midfield. I wanted them to get on the ball and be creative. I didn’t see that from any of them. [Georginio] Wijnaldum, no. [Jordan] Henderson, no. [Naby] Keita, no.”

Niall Quinn, working alongside Souness for Virgin Media Sport, suggested Klopp may have been annoyed because the Bayern Munich players were time-wasting during the closing stages of the match.

“He’s complaining I think about the players taking too much time, three or four of them went down in the last five minutes to see the clock out,” Quinn argued.

Souness, however, was not having this as the explanation behind Klopp’s altercation with Kovac.

“It’s not worth going down that road,” Souness bit back. “He’ll be frustrated. He’s not got a result, he’s not got a victory. He knows, because he’s German, how hard it is to get a result in Munich.”

Maybe both Quinn and Souness were right.

It’s possible Klopp was frustrated with both the time-wasting of the Bayern Munich players and his own team’s failure to take an advantage ahead of the second leg at the Allianz Arena in three weeks’ time.
