Jose Mourinho has been fined £25,000 and warned over his future conduct by the Football Association for claiming there was a "clear campaign" against Chelsea.
Mourinho's complaints came following the draw at Southampton on December 28th, and were found to have brought the game into disrepute.
An independent regulatory commission also ruled that the comments did not necessarily imply officials were biased against Chelsea.
Chelsea have told Roma they will only allow winger Mohamed Salah to leave this month as part of a permanent deal worth over £11m.
The Blues were not expecting to do any major business in January but are prepared to sell Salah, who is yet to start in the Premier League this season.
Roma had hoped to take Salah on loan but Chelsea have told the Italian giants they would have to make the switch permanent at the end of the campaign.
Chelsea are demanding £760,000 for an initial six-month loan spell, with an obligation to pay another £10.6m in the summer.
The deal would see the Blues recuperate the fee they paid Basel to sign Salah just 12 months ago.
It is understood, however, Roma view that package as too expensive for a player who has managed only two goals in almost 14 months.
Jose Mourinho has repeated his plea for a noisy Stamford Bridge when Chelsea play Liverpool next week for a place in the League Cup final.
The Blues drew 1-1 at Anfield on Tuesday night and play the Reds in the semi-final second-leg bidding for a place in the March 1 final at Wembley.
Mourinho, who won the League Cup twice in his first spell at the club, was critical of Chelsea fans following November's win over QPR, saying he felt his side were playing in an "empty stadium".
The Portuguese believes a partisan crowd can make a big difference next week against Brendan Rodgers' visitors.
It was a two-leg semi-final, now it's a one-leg semi-final. That says a lot.
Two legs is difficult, Anfield is difficult and with this result we transform a two-leg semi-final into a one-leg semi-final at Stamford Bridge.
If Stamford Bridge can give us 25 per cent of the emotion Anfield gives Liverpool, I think we can do it. Liverpool, instead of 40,000 fans, they will have five or 10 (thousand).
Chelsea, instead of 1,000, will have 40,000. I hope that can make a difference in the atmosphere.
Jose Mourinho was offered the chance to sign Angel Di Maria and Radamel Falcao last summer, but turned down the opportunity through fear of causing "an explosion" at Chelsea.
The Special One has the same agent - Jorge Mendes - as Di Maria and Falcao, but didn't want to pay the pair's astronomical wages because he felt it would have caused unrest at Stamford Bridge.
Speaking to the Sun, Mourinho said:
Jorge told me Di Maria and Falcao are his players and he has to find solutions for them," Mourinho is quoted as saying by The Sun, who carry extracts from the book The Key to Mendes. Radamel Falcao is earning a reported £260,000-a-week.
But if Chelsea doesn't have the financial capacity to pay eight, nine or ten million euros a year, because of [financial] fair play, of course Mendes has to think about his players.
We couldn't bring Falcao or Di Maria because I didn't want to, either. I can't have a player earning 10 million when others earn three, four or five. That would have caused an explosion.
Mario Balotelli and Cesc Fabregas have locked horns ahead of this evening's League Cup semi-final first leg.
The pair will meet at Anfield when Liverpool host Chelsea in the cup competition, but were keen on settling their own personal duel beforehand for Puma's latest viral advert.

Jose Mourinho often boasts about his formidable record against the big teams, but it's a different story when he comes up against Liverpool in the cup.
The Portuguese manager won just two of his nine cup competitions against Liverpool during his first stint at Chelsea, with one of those victories coming in a Champions League semi-final first leg encounter.
Mourinho's men went on the lose the second leg in 2007 by the same 1-0 scoreline and were dumped out on penalties.
The Special One's high-flying Blues travel to Liverpool on Tuesday with Mourinho hoping to eradicate his unfavourable record.
Mourinho's record against Liverpool in cup competitions:
- Played: 9
- Won: 2 (League Cup final in Febraury 2005, Champions League semi-final first leg in April 2007)
- Drawn: 3 (Champions League semi-final first leg in April 2007, Champions League group stage in September 2007, and December 2007)
- Lost: 4 (Champions League semi-final second leg in May 2007, FA Cup semi-final in April 2006, Charity Shield in August 2007, Champions League semi-final second leg in April 2007)
Jose Mourinho has urged Chelsea fans to stop giving Steven Gerrard a hard time over his costly slip at Anfield last season.
Liverpool's captain fell over with the ball at his feet when Chelsea visited Anfield in a crucial Premier League clash in April 2014.
The Blues broke away and took the lead, eventually winning the fixture 2-0 and effectively ending Liverpool and Gerrard's hopes of collecting his first ever league title.
Chelsea fans will travel to Liverpool in their thousands for Tuesday's meeting, but Mourinho wants them to scrap any chants directed at Gerrard.
Gerrard is an historical player for Liverpool, an historical player for the Premier League, an opponent I always admired and respect. Our fans have a song (about him) that I don’t like, I don’t like it at all.
Maybe a couple of times it’s good fun, but to go on and go on, especially when a player like him deserves respect, I don’t think we need that. We have so many other songs that we don’t need that one.
I love those quotes when Gerrard was saying that, in this life, he would never score against Liverpool. I understand why he was almost, almost, almost coming to Chelsea, and he didn’t. I respect that a lot.
The decision (to stay at Liverpool) for me was proven right because he will always be a Red for ever.
