Never thought I would see Steven Gerrard getting slated on a Liverpool forum.
Personally, don't think there is much wrong in what he is saying, apart from may be being a tad bit too honest.
Regarding Rafa, I don't think he is being disrespectful at all. He has stated unequivocally that Rafa is the best manager he has played with and praised his coaching abilities. What he is commenting on is the personal side of his relationship with Rafa, which wasn't very warm. Big deal. So Rafa was cold, professional and effective - not a news this.
Rafa was right in whatever he did and Gerrard is right in having his opinion. To be fair, at least the frank honesty gives an insight into things we have only speculated about so far.
The writing sure is quite cheesy.
