Borussia Dortmund boss Jurgen Klopp has jokingly vowed to "shut up" in response to Real Madrid coach Jose Mourinho's claim that he has not stopped talking since their two sides were drawn against one another in the semi-finals of the Champions League.
The Portuguese stated that Klopp had been speaking to the media on a daily basis while he, by contrast, had been maintaining a dignified silence ahead of Wednesday night's first-leg meeting at Signal Iduna Park.
"Mourinho says I talk a lot?" he mused after Dortmund's 2-0 win over Mainz on Saturday. "That's what one of my teachers used to say. I'll shut up, then!"
Klopp, though, was more than happy to discuss a victory that guaranteed his side a place in next season's Champions League.
The recently dethroned Bundesliga champions had not been at their brilliant best against Mainz, but an early effort from Marco Reus and a late goal from Robert Lewandowski secured the hosts the most straightforward of victories.
"We have rarely found the game as easy as we have today," Klopp was quoted as saying by his club's official website.
"Our first attack brought us the lead and for the next 20 or 25 minutes, we were really great. Then, we lost our way a bit, and Mainz were somewhat stronger. We were lucky that they did not equalise.
"But we have exprienced games like this before so we adjusted a bit during the break and then played an intense second half to win the game.
"Also, nobody got injured, so it's been a perfect day for us."
Defender Marcel Schmelzer was just as enthused by the win, primarily because it ensured Dortmund will be back in the Champions League next season, irrespective of the outcome of their semi-final showdown with Madrid.
"Yes, that is very important," he told RuhrNachrichten.de. "We have always stressed that this was our primary goal for the season.
"Also, now we don't have to read questions about how we're supposed to beat Madrid when we cannot even focus properly on the league.
"It was always very important to us that we focused fully on the game immediately in front of us, and we managed that today."
Dortmund defeated Madrid when the two sides met at Signal Iduna Park in this season's group stages, before drawing at the Santiago Bernabeu.
