Jose Mourinho claimed there is one rule for Chelsea and another for Manchester United on penalty decisions after watching his side miss the chance to close the title race gap to one point against Newcastle.
Mourinho vented his frustration after referee Mark Halsey had turned down two Chelsea penalty claims in the goalless draw at St James' Park.
The Chelsea manager was already aggrieved that United had escaped defeat against Middlesbrough 24 hours earlier when referee Peter Walton ignored strong claims for a penalty when South Korean striker Lee Dong-Gook was felled by John O'Shea in a 1-1 draw at Old Trafford.
Had all three decisions gone Chelsea's way Mourinho's side could potentially be level with United instead of being three points adrift.
'One rule is not to allow penalties against Man United and another says none in favour of Chelsea,' he told Prem Plus. 'You are speaking about big decisions which affect points.
'We can speak about the game we saw or the game that could be if Chelsea is winning 1-0 (had they been awarded an early penalty at St James' Park).'
Referring to the Lee Dong-Gook incident at Old Trafford, he added: 'They cannot lose. Yesterday it was a penalty in the last minute and they are forbidden to lose.'
Mourinho also reiterated his desire to stay at Stamford Bridge next season and claimed that chief executive Peter Kenyon's public backing earlier this week should mean any doubts about his future are at an end.
'I said many times in the last few months that I want to stay,' he told Prem Plus.
'They (the board) have told me they want me to stay and not leave, and end any speculation.
'I have worked with them for three years and I believe what they say.
'When they want me to stay and I want to stay that is the end of the story.
'Between us everything is clear.'
Mourinho admitted his side did not deserve to take three points from today's game.
The Blues dominated the majority of the match but failed to create clear-cut chances against a resolute Newcastle defence.
'If you ask if Chelsea deserve to win this game, I don't think so,' Mourinho added. 'Newcastle were fresher and were dangerous on the counter attack.
'They deserve to get their point.'
Despite seeing his side spurn the opportunity to move within a point of Manchester United, Mourinho claimed he was content to go into the final four games - three of which are at Stamford Bridge - still in touch at the top.
'Our target for weeks has been to finish this period with a situation where we could do it (win the title) and I would have been very happy with this situation 10 weeks ago,' he said.
'We are in a position to fight for the Premiership. One win is not a lot.'
