Certain players on Chelsea are concerned with the scapegoating Jose Mourinho has been engaging in after their tough start.

Oscar and Loic Remy weren't taken to Porto, while John Terry's continued absence has come as a surprise to senior squad members.

Mourinho also dropped Eden Hazard and Nemanja Matic from the starting XI at Porto though both were brought on as subs.

Borussia Dortmund sporting director Michael Zorc believes Jurgen Klopp could become the next Bayern Munich manager, telling Sport Bild ahead of Der Klassiker: "It's factually conceivable."

Klopp has previously said he would be open to accepting the Bayern job and has been strongly touted to replace Pep Guardiola when his three-year deal expires in 2016.

Dortmund CEO Hans-Joachim Watzke said last month that Klopp would be a "100 percent suitable" replacement for Guardiola.

Klopp reportedly rejected an offer to become manager of Mexico's national team.

Louis van Gaal is due to retire in 2017 but he's opened the door about staying on longer at Manchester United.

Van Gaal said it's difficult to step away once you get "the bug."

“Normally I shall leave after next year but what is normal in our football world?” Van Gaal said. “You never know, so I cannot answer that question, but I did promise my wife to go with her to our paradise, so it shall be very hard for me to deny her that promise.

“I was 55 [when I first said I would retire] and then I went to Bayern Munich and next year I am 65. If I say I want to stay a year longer it shall be very hard for my wife.”

Van Gaal calls paradise his holiday home on the Algarve.

Ryan Giggs is widely considered manager in waiting upon Van Gaal's departure.

Carlo Ancelotti remains on sabbatical after his dismissal from Real Madrid.

Reports have emerged of Liverpool's interest in Ancelotti, but he has told people he has received no word from the club.

Ancelotti is actually more interest in the Manchester United job, though Ryan Giggs is widely considered to be next in line when Louis van Gaal leaves.

Ancelotti is living in Vancouver where his wife is from.

Porto have consistently played the transfer market as well as any club in the world, selling players at a great profit.

James Rodriguez, Hulk, Radamel Falcao and Pepe are some of Porto's most well-known transfers.

Vincent Aboubakar, Yacine Brahimi, Ruben Neves and Giannelli Imbula are four players most likely to command large fees in the near future. 

Aboubakar is Porto's main striker following the departure of Martinez.

Brahimi is a skilled winger that had 164 take-ons in La Liga during the 13-14 season.

Neves is just 18 and could be used at the base of a midfield.

Imbula is a promising box-to-box player.

Gonzalo Higuain's agent claims he remains happy at Napoli despite growing interest from Arsenal and Liverpool.

Higuain was strongly linked to a move this past summer following Napoli's inability to qualify for the Champions League.

And after six games of the new season Higuain's agent and brother, Nicolas, claims he's settled in Naples.

"He's happy with (Maurizio) Sarri," Higuain told Radio Crc.

"Everyone wants to play football, and the important thing is that he's calm, he's realised what Sarri wants and now he just has to remain calm and focused.

"It's been a major change and he's responding well to the demands of the coach. Gonzalo is doing the maximum with Sarri."

Wayne Rooney denies making a transfer request to Manchester United in 2013.

Rooney did admit, however, he discussed a potential exit with Alex Ferguson.

Ferguson had announced in October 2010 that Rooney had expressed a desire to leave the club only for the forward to commit to a new five-year contract later that month, but there were further issues in Ferguson's final season and the United boss told the media in May 2013: "He has asked for a transfer."

Speaking in the forthcoming BBC documentary "Rooney: The Man Behind the Goals," the England international has stressed that he did not formally request a move but said he did tell the manager he was unhappy after finding himself behind Robin van Persie in the pecking order in the 2012-13 season.

Rooney said: "I went in to see him and just said, 'If you are not going to play me then it might be better for me to move on.'

"Then, all of a sudden, it was all over the press that I had put a transfer request in, which I never did. I don't know what happened, why that came out that way."

Neymar's agent encouraged him to use tax havens and also end his career with Real Madrid.

Neymar has reportedly evaded 63 million reals in Brazil taxes (almost $16 million) between 2011 and 2013, when he was still a player with Brazilian club Santos.

"Take your money, send everything to tax havens, legally, of course," Wagner Ribeiro wrote in a letter addressed to Neymar's father, Neymar Sr. "This way you will stop paying taxes in Brazil! Close your businesses, the Institute of Praia Grande, and go enjoy your life on Mediterranean beaches. You and your family.

"But leave Neymar to play a few more years ... and end his career in Europe, preferably at Real Madrid."

Diego Costa fears he is being forced out of the Premier League.

Costa is under a three-match suspension for his role in Chelsea's 2-0 win over Arsenal.

“Costa feels he is being picked on a little,” a Chelsea source told Football Insider. “No one seems to have mentioned the fact that he has not been sent off during a competitive match for four years.

“He has always been a physical player who gives as good as he gets but he thinks there could now be agenda against him because of who he is.”

Football Insider previously reported Costa has interest in returning to Spain and has a strained relationship with Jose Mourinho.

Manchester City increased the wages of Kevin De Bruyne by a factor of four during his move from Wolfsburg.

Wolfsburg were desperate to keep De Bruyne in the transfer window, but eventually opted to allow him to move on after all when City met their asking price of around £55 million.

Sporting director Klaus Allofs told Die Welt: "We spent a long time weighing up all our options and trying to keep Kevin at Wolfsburg. But at some point, we reached the conclusion that it would be best to allow him to move.

"When a player has an offer from another team where can make four times as much money, you have to take into account what such an offer does to a player.

"Kevin received an offer that could very well be a once in a lifetime opportunity. There is no guarantee that he would ever get such a offer again.

"We have certain limits that teams like Manchester City, Paris Saint-Germain, Barcelona or Bayern Munich do not have. It is totally unrealistic to claim that nobody can lure players away from us."
