What on earth has gotten into Mino Raiola?
For someone who remained so quiet throughout the summer transfer window, there's now no stopping the Italian-born Dutchman from speaking his mind.
It all started in late August, when the super agent revealed why Paul Pogba decided to join Manchester United instead of Real Madrid.

Then, he confirmed that Zlatan Ibrahimovic's heart is at AC Milan and how the Sweden international was intent on securing a return to the San Siro this summer.
And most recently, before claiming football's first £200 million player will happen within the next two or three years, Raiola labelled Jurgen Klopp a "piece of s**t" for his treatment of Mario Balotelli at Liverpool.
He's been at it once again on Thursday morning, this time slamming Manchester City manager Pep Guardiola for 'not having the balls' to speak to him face-to-face.
"I don't hate him... because hate consumes you. But I don't like him. He's a good coach but his football is a bit boring to me.
"Me, I'm a professional. I want to do the best for my clients. He? He doesn't have the balls to sit down with me."
Raiola's fury stems from Guardiola shipping his client, Zlatan Ibrahimovic, on loan to AC Milan from Barcelona in 2010, later selling the Swedish striker for €24 million.
Ibrahimovic's relationship with the Spanish manager quickly deteriorated at the Camp Nou, with one particular incident epitomising that notion.
Following Barcelona's exit in the 2010 Champions League semi-finals, the pair apparently came to blows in the dressing room.
"Guardiola was staring at me and I lost it," Ibrahimovic said, in quotes relayed by Sky Sports. "I thought: 'There is my enemy, scratching his bald head!'
"I yelled: 'You haven't got any b***s!' and worse than that I added: 'You can go to hell!' I completely lost it, and you might have expected Guardiola to say a few words in response, but he's a spineless coward.
"As it is now, [I wouldn't work with him again], because I don't have answers about what happened.
"As a coach, he was fantastic. As a person, I've no comments about that, that's something else. He's not a man, there's nothing more to say."
Regardless of Ibrahimovic and Guardiola's frail relationship, here's hoping this is the last time we have to listen to Raiola rant unnecessarily.
