Other than the part where Mourinho doubted RLC's injury and said their relationship has taken a step back, I don't think there's much wrong with what he said. The only issue is, did he really need to say it in the public, after a post-season friendly? If RLC has been slacking off for ages, then I can perhaps understand it but it happened once when other times he has done alright. Could have just said to him behind closed doors, just like he would have done in every training session, team talk etc.
