The Queens Park Rangers midfielder has been pleasantly surprised by his captain.
Barton's troubled footballing past is well documented; one needs only to search an image of Ousmane Dabo's injured face after an altercation with Barton for proof.
But there has been a definite change to the QPR midfielder in recent times. Whether that change is definitive or not only time will tell - but there has definitely been a maturing, at least temporary, from the 32-year-old, now a leader from midfield in west London.
Not only has he been a leader of late, Barton acted as peacemaker when Clint Hill and Fer were involved in a verbal spat with QPR fans during the 2-1 defeat at Burnley
And Fer says his opinion of the midfielder has changed markedly as a result, as he gets to see the real side of his team-mate.
"“For the first six months he has been like that with me," the Dutchman is quoted as saying.
"Everyone said before I joined that Joey Barton is crazy and this or that, but no - he’s been a really good captain. He calms people down, he talks a lot with me. I don’t have the impression that I had before of him.”
QPR host Manchester United at Loftus Road tomorrow afternoon at 3pm British Time.
