This week will not have gone down as one of the best in Manchester United manager David Moyes' life after successive home defeats to Everton and Newcastle United.
And now the Old Trafford boss has had to deny suggestions that striker Robin van Persie has handed in a transfer request, while another leading European coach has been linked with replacing him in one report.
Things are a lot sunnier at Arsenal, though, where manager Arsene Wenger is weighing up a move for Everton right-back Seamus Coleman, according to a report on Sunday.
But who else is making the headlines on Sunday? Read on to find out more.
Manchester United manager Moyes has denied that star striker Van Persie has made a transfer request, reports Gary Jones of the Daily Star Sunday.
Former Liverpool defender Mark Lawrenson had claimed on Saturday in a radio interview with Irish station Today FM that speculation Van Persie had asked to leave the club was rife, as Jones reported for the Daily Star.
Meanwhile, Borussia Dortmund head coach Jurgen Klopp has been installed as favourite to succeed Moyes at Old Trafford, claims Greg Heffer of the Daily Star Sunday.
Despite his current concerns at United, Moyes is adamant that United will still be chasing the Premier League title by the end of the season, reports Neil Custis of The Sun (subscription required).
And the under-fire United manager has lined up a move for Roma star Kevin Strootman, claims Paul Hetherington of the Daily Star Sunday.
Arsenal manager Arsene Wenger is considering a transfer move for Everton defender Coleman if Bacary Sagna does not sign a new contract, claims Alan Nixon of the Sunday People.
But the Emirates Stadium transfer links don't stop with the Republic of Ireland international, according to the Sunday newspapers.
The Gunners are locked with Liverpool in a race for Hamburg midfielder Hakan Calhanoglu, reports Alan Nixon of the Sunday People.
Former Arsenal defender Alex Song could be available for a return to north London from Barcelona for £10 million, claims Ben Burrows of the Sunday Mirror.
Fulham striker Dimitar Berbatov has emerged as a January transfer target for Wenger, claims Rob Shepherd of the Mail On Sunday.
And Greece striker Konstantinos Mitroglou is also being considered by Arsenal, says the Daily Star Sunday.
Manchester City manager Manuel Pellegrini is considering a sensational transfer move for Bayern Munich goalkeeper Manuel Neuer, reports James Desborough of the Sunday Express.
The Germany international will line up for the European champions against City and Joe Hart in the Champions League this week.
Meanwhile, Pellegrini is expected to play a second-string team against Bayern as he rests players ahead of the Premier League clash with Arsenal next weekend, reports Simon Mullock of the Sunday Mirror.
Mullock also reports in the same newspaper that City will not consider allowing forward Stevan Jovetic to make a loan move to Serie A next month.
Real Madrid have reassessed their valuation of City striker Sergio Aguero to £60 million, reports Steve Millar of the Daily Star Sunday.
Liverpool striker Luis Suarez will make England pay for the treatment he has received in the Premier League when the 2014 World Cup gets underway, according to Uruguay assistant coach Celso Otero Quintas, as Steve Bates of the Sunday People reported.
The Anfield forward has been in excellent form since returning from a 10-match suspension for biting Chelsea defender Branislav Ivanovic last April and was previously suspended for eight matches over a racism incident involving Manchester United defender Patrice Evra.
Now Quintas believes Suarez will gain revenge for the perceived slights against him when he lines up for Uruguay against England in the 2014 World Cup:
Luis has shown his exceptional talent since he has been playing in England.
But what he has also shown is great strength and resistance against a flood of ‘information’ intended to put him down and belittle him.
I also think, little by little, he is winning around the English public, and they are at least showing him the respect he deserves.
That’s about time because he is a fantastic footballer and does not deserve the treatment he has been given.
What happened to him was an issue between the player and the English football establishment.
Netherlands head coach Louis van Gaal has criticised FIFA for turning the 2014 World Cup draw into a "circus" and disrespecting the late Nelson Mandela, reports Anthony Clavane of the Sunday Mirror.
World governing body president Sepp Blatter cut short a minute's silence for Mandela before the draw, and Van Gaal was unimpressed, according to Clavane:
That was a shameful action.
Mandela means so much to so many people all over the world. I did not agree with it.
It (the draw ceremony) was just one big circus.
It cost £8 million to stage. Money that could have been spent on charity, in my opinion.
This whole draw is one big fake.
West Bromwich Albion are keen to bring Manchester United winger Wilfried Zaha to The Hawthorns on loan next month, reports Alan Nixon of the Sunday People.
Newcastle United are weighing up a move for Norwich goalkeeper John Ruddy, claims Alan Nixon of the Sunday People.
The unsavoury subject of match-fixing has again hit the headlines, with Mazher Mahmood of The Sun (subscription required) reporting two unnamed former Premier League players are involved in the latest allegations.
