Last season's top goalscorer Diego Costa looks set to leave Chelsea, having fallen out with Italian coach Antonio Conte.
The Spanish international received a text from Conte at the end of the season, informing him that he is no longer in his plans at Stamford Bridge.
Costa is desperate to return to Atletico Madrid and has been involved in a stand-off with Chelsea after refusing to return from his summer break in order to train with the reserve team.
He was signed for £32m from Atletico in 2014 but the Spanish giants are allegedly struggling to meet the price-tag set by Chelsea.
The 28-year-old frontman has excelled during his time in London, netting 52 Premier League goals and winning two league titles.
With the 2018 World Cup looming, Costa wants his future sorted by August 31st and gave a couple of explosive interviews last week in a bid to speed up proceedings.
He insists that he's been treated like a 'criminal' by Chelsea and suggested that their valuation of him was far too high.
Costa appears to have lost the support of the Chelsea fans amidst the bizarre summer saga but former Blues manager Ruud Gullit believes the blame lies with Conte.
The 54-year-old Netherlands assistant manager was a player-manager at Chelsea between 1996-1998.
Gullit insists that the Italian coach made a mistake with his text and should front up and apologise to the eccentric striker.
The Dutch manager turned pundit famously fell out with Alan Shearer during his time as manager of Newcastle United.
"It's all been instigated about what happened with Diego Costa," said Gullit.
"It's a little bit strange that you hear at the end of the season that you're not welcome, and now he's training somewhere in Brazil and that's not good for Costa, not good for the club, not good for anyone.
"(It was) not very wise to do. You don't do that. I think it is a mistake by Conte and I hope that he has learnt from it.
"He still has the possibility to do something about it, just got to him and say, 'I'm sorry that I did it, you have to come back, we will talk'.
"You need to see each other face to face. You don't need to like each other, but you need to respect each other. If he doesn't want to come back then you have to find the best solution for the club."
