Jurgen Klopp endured a night to forget last evening as Borussia Dortmund slumped to a 2-0 defeat against Arsenal in the Champions League, the latest loss in a miserable season for the Bundesliga club.
And things got even worse when the easy-going manager was seen arguing with one of his players following the full-time whistle at the Emirates Stadium. Under Klopp, Dortmund have claimed two Bundesliga titles and reached the Champions League final in 2013 - however things are not going to plan this term.
So far they've won just three of their 12 league games to leave them two points from bottom, and 19 points off of Bayern Munich at the top of the table. Europe has offered some respite however and going into last night's game Dortmund were sitting pretty at the top of Group D with maximum points from their first four games.
However the sanctuary offered by Europe's top club competition was whipped away by Arsenal, who swept into a 1-0 lead inside the first five minutes before Alexis Sanchez finished things off with a wonderful curing strike in the second half.
While Dortmund remain top by two points from the Gunners with one game remaining, Klopp was visibly furious with his team's efforts, and took his frustration out on one player in particular.
Ramos was a substitute for Pierre-Emerick Aubameyang just after the hour mark, but the former Hertha Berlin striker bore the brunt of his manager's angst as the two became embroiled in a heated argument after the final whistle.
Afterwards, Klopp admitted he was unhappy with his team's performance, saying there were a 'thousand things wrong' with their effort. 'It was the worst possible start to concede such a quick goal," he said.
There were situations and moments when we did what we wanted but those periods were very short. Too many times we were not that great and Arsenal were the deserved winners tonight. We just weren't good enough.
'We could have done better, we were not courageous tonight. There are 1,000 reasons why we were not that good tonight. We have to work. 'That's the plan. Work always works in life. We don't party between the games, we always try to improve things.
"We have to admit we are not as confident as in positive periods but you can work hard to get to deserve the luck in life. We will get it back. We don't need the perfect football, we just need good results.'
Dortmund will try and get the win they so desperately need when they take on Eintracht Frankfurt on Sunday.
