Me too, knowing Roman.
No owner is going to let a coach say that and have a job. NONE.
Yeah, that's what he said: "I really feel disappointed with a group of fans, because they don't do any favours to the team. They should support the players instead of wasting time preparing banners or singing songs [against him]." He's saying a vocal group of fans is putting more effort into whining about him then they are into cheering for their team. Which is true...they strolled to a 2-0 win today and some fans were still chanting against him. That's bush league.
I didn't see the match, but all of this came as a surprise to me. Normally, if the fans are chanting anti-Rafa stuff, there are a lot of tweets about it on my timeline. The only time I saw it mentioned was the 16th minute RDM chant. So I don't know what was being sung, but don't assume it was happening more today than normal.
